Nginx as a Magento web server

Magento Nginx configuration  

Official manual on Magento wiki

You can always use LAMP as a simple hosting solution for your Magento store, but there are cases when Apache with mod_php is not the optimal idea. For example, if your e-commerce Magento store has a dynamic content generated by PHP scripts additionally to static files. In this situation Nginx with PHP-FPM can be useful in order to improve the performance of Magento.

For simultaneous HTTP/HTTPS connections, Apache uses a large amount of RAM and CPU cycles. The problem is particularly acute for standard Apache configuration and the mod_php prefork. Since each Apache child process requires around 100MB RAM for every request in general, a dedicated 16GB RAM web server is limited to just 150 concurrent requests.

The major advantage of Nginx is that it is event-based while Apache is process-based. Thus, Nginx doesn’t require any new process to increase the level of concurrency. As a result, the memory footprint of Nginx is very low. In addition, we should mention, that Nginx exploits asynchronous and nonblocking I/O.

Moreover, Nginx is operated by a pre-set number of worker processes, and each of them exists in a form of a single isolated process. Thanks to event-driven and non-blocking architecture, Nginx allows every single worker process to handle requests by multiple clients.

You can benefit from Nginx even if you aren’t going to handle thousands requests at the same time. This server solution scales in all possible directions: from the smallest VPS to servers’ clusters, offering rapid Magento performance.

Nginx handles about 10 thousand HTTP/HTTPS requests per second and uses just 10-20 MB of RAM and 10-15% of average CPU. Keep in mind, that in case of HTTPS, the usage of CPU will be higher because of decryption/encryption routines.

The biggest drawback of Nginx is the absence of mod_php or its analogs designed to  execute PHP apps directly. Being a static content web server and a reverse HTTP/ FastCGI proxy, Nginx can’t run Magento directly. To do so, it must use another means. The most reliable solution of this problem is PHP-FPM, which is designed to run high-load websites with PHP web apps. PHP-FPM consumes a small amount of resident memory and offers some unique features, such as adaptive process spawning; advanced logging with slowlog for slowly executing PHP scripts; ability to start workers with different php.ini and different uid/gid/chroot/environment; emergency restart for accidental opcode cache destruction; real-time data on performance and server activity.

Magento performance improvements: Nginx

To use a Nginx with your e-commerce Magento store, you need a frontend with:

  • Caching
  • Reverse FastCGI proxy which handles all HTTP/HTTP connections
  • All static file delivery

In this case, Nginx performs as a reverse FastCGI proxy for all dynamic content requests. All the requests are proxied to a backend PHP-FPM app, and after a response are delivered back to the visitor.

Use Nginx as a load balancer (one Nginx frontend + several PHP-FPM backends) provides backend failover and both high scalability and availability for the Magento installation. In addition, there is no need to use a hardware load balancer or any other associated expenses in this case.

Monitoring tools and analyzers

Low Magento performance leads to slow pages and negative user experience which could be a reason for your potential customers to leave the webstore before they even get to the checkout. Luckily, there are a lot of different monitoring tools and analyzers, designed to identify the problem in time.

New Relic

You can use New Relic to mark different operations as key transactions, which serve as triggers for custom alerting. Another function of this tool helps to observe the slowest queries. Thanks to “app map” feature, New Relic provide a clear view of the application dependencies which occur on your Magento e-commerce site. This feature also works for  third-party extensions and external services. With the “app map” feature, you will find the “weakest link” in your application chain with ease. Last but not least are Apdex scoring and Alerting. With the help of Apdex scoring, New Relic evaluates how well Magento app is performing according to an industry standards. The feature is combined with alerting, so you will be always notified when your Magento performance is challenged due to different reasons.

With the AppDynamics platform, you will get a full visibility of the Magento based PHP app performance. The solution provides rapid installation and high scalability. AppDynamics automatically discovers Magento application topology. The tool provides the ability to customize monitoring process by choosing which transactions to include or exclude from real-time view. It also distinguishes web and mobile experience, and expands visibility from the user to the database by correlating performance of the database to originating transaction performance metrics. In addition, you will get a visibility of the errors and exceptions root cause in a real-time.

Magento MySQL optimised configuration

A proper MySQL configuration is among the most important enhancements to Magento performance. It requires an understanding of your hardware – primarily the available RAM. Below, you will find the most reliable solutions, designed to optimize Magento and enhance your website’s performance with the help of proper MySQL configuration.

The example of proper MySQL configuration:

Magento Performance: Know Your Database

In this presentation, Ivan Chepurnyi describes how to set up a MySQL database. He offers 4 effective tricks, which will help you increase the performance of your Magento website significantly.

MariaDB instead of default MySQL

MySQL is not a necessity, so you can always move out of it, while trying to improve your Magento performance. These are two popular alternative solutions: MariaDB and Percona. First one is a fork of MySQL developed by the community. MariaDB was created under the GNU GPL from the original creators of MySQL. Its intents are:

  • maintaining a high MySQL compatibility;
  • ensuring a “drop-in” replacement capability with library binary equivalency;
  • matching with MySQL commands and APIs.

MariaDB instead of default MySQL

MongoGento by Smile Open Source Solutions

There is also an opportunity to use NoSQL database instead of MySQL database. All you need is MongoGento by Smile Open Source Solutions. This module provides your e-commerce Magento store with the ability to use MongoDB. As a result, you will reduce the size of your database and the impact of Magento EAV model. That is because of heterogeneous catalogues, designed for millions of products. At the same time, you retain the flexibility of the familiar document model.

Another strong point of MongoGento is its performance and consequently the performance of Magento. The combination of a SolR, MageCache, and MongoDB makes both frontend and backend extremely fast. It is also necessary to mention, that MongoGento is open source, scalable and secure alternative to MySQL with a quick installation.

The only drawback is a conflict between MongoGento and some other modules. For example, product catalog rules are not able to handle some attributes. For more detailed information, go to MongoGento’s GitHub or official page.

How to use Redis with Magento

Redis (REmote DIctionary Server) is an open-source, networked, in-memory data structure server which stores keys with optional durability. Being one of the most popular key-value stores, Redis is suitable for the Magento. E-commerce platform currently provides the support for many cache backends with file systems, but with a growing number of requests, such cache backends provide terrible scaling. Moreover, some of them suffer from other limitations. For example, they don’t have any support for related cache entries grouping. To solve this problem, you can tune your ecommerce website to Redis, improving Magento performance

Why Redis?

Nowadays, Memcached has no significant advantages over Redis. Both solutions are extremely fast as volatile caches, but all major features of Memcached are now offered by Redis. In its turn, Redis continues to surpass Memcached. Latest version of Redis offers clustering out-of-the-box. The other useful tools are replication and Sentinel. With their combination, Redis has much more advantages than Memcached. These are the features which turns Redis into a real data storage (not just a cache as Memcached):

  • Powerful data types with powerful commands: Sorted Sets, Hashes, Lists, etc
  • Default persistence to disk
  • Optimistic locking transactions (WATCH/MULTI/EXEC)
  • Extremely fast Pub/sub
  • Values are limited to 512MB (1MB per key in case of Memcached)
  • Built in clustering (as of 3.0)
  • Lua scripting (as of 2.6)
Magento performance improvements: Redis


Redis is more flexible than Memcached.  It provides higher scalability, availability, and administration. Redis is not only a better solution for places where you can use memcached, it is suitable for a lot more types of use cases. Hence, it is a better option to increase Magento performance.

The process of Redis implementing as a cache and session backend within Magento is described at Inchoo:

We recommend you to check both articles to find out all the nuances. And don’t miss this PDF tutorial:

There are also two useful projects on a GitHub. First one is Cm_RedisSession. It is a Redis-based session handler designed for Magento. Cm_RedisSession has a lot of useful features. Hit the below link for the detailed description of this tool. You will also find installation tutorial and the example of configuration.

With Cm_Cache_Backend_Redis, you will get a Zend_Cache backend using Redis which provides a full support for tags. The backend make it possible to turn a Redis server into a central cache storage. Keep in mind, that with Cm_Cache_Backend_Redis a tags full support doesn’t require the use of TwoLevels cache. Thus, this backend suits best for use in a cluster or on a single machine. Cm_Cache_Backend_Redis works with any Zend Framework project, all versions of Magento are supported.

How to use CDN with Magento

Сontent delivery network or CDN is a complex of servers with multiple data centers around the world and across the Internet. The main goal of every content delivery network is to provide content to end-users with the highest possible performance and availability. CDNs work with different web objects and store downloadable content. They also provide faster access to apps, streaming media, and social networks. Thus, CDNs play an important role in a modern online content delivery, and could be a perfect improvement to Magento performance. There are dozens of possible solutions, but we recommend you to pay your attention to CloudFlare.

Final Words

Performance is extremely important for every website, and e-commerce web stores are not the exception. Statistic differs from market to market, but the negative impact of slow speed is obvious. According to, in 2013 slow websites should cost UK online retailers more than £8 billion. At the same time, there is information about $3 billion of lost e-commerce sales for the US market.

Website performance tests by shoved, that over 90% of 230 leading online retailers were failing to meet the industry’s benchmark of 3-second page load. Furthermore, some were running as much as 8 seconds. But how does this affect visitor’s behavior? 44% of online customers think, that the transaction is failed if the checkout is slow. As a result, many of them (33%) look for e-commerce stores with better performance or abandon their carts. Transaction with a delay of just 2 seconds results in a high shopping cart abandonment rate, which is over 80%.

The below infographic by OnlineGraduatePrograms shows how average US web user reacts on websites with slow speed. Some of the statistics show, that 25% of people abandon a website if its page load time takes longer than 4 seconds. The situation with mobile shopping is even more dramatic. 40% of Americans leave m-commerce sites that won’t load in 3 seconds.

Utimate Guide to Magento Performance

Surprising as this impatience may be, its implications are even more shocking. According to Amazon’s research, a second page load slowdown could cost more than $1.5 billion in sales during the year. In its turn Google tells that by slowing search results by 0.4 of a second the company could lose 8 million searches every day.

There are new and existing consumers on every e-commerce web store. Thus, we can speak about two types of interaction – first view and repeat view. Both have three specific metrics: time to first byte, render start, load time.

With the time to first byte, you measure the amount of time required for the servers to react to the request of a browser to send data. With the render start, you measure the amount of time necessary for the first page element to be displayed on the browser.   Load time means the total amount of time required to load all elements of the page.

The above metrics should be measured under both normal conditions and conditions of stress. You can use to do this. The reporting will indicate what is slowing your e-commerce site down.  The most common reasons are heavy images and interactive page features, site build shortcuts, poor hosting environment. These are Amazon’s results for the first view:

  • First Byte: 0.285 sec
  • Render Start: 0.944 sec
  • Load Time: 2.071 sec

These are for the second one:

  • First Byte: 0.285 sec
  • Render Start: 0.833 sec
  • Load Time: 1.346 sec

Such results are the example of top page load speed metrics to some extend.
