Varnish

Varnish Cache is a web application accelerator, developed and made available freely by Varnish Software. Depending on the application, it can result in a boost of 10x up to 1000x. With Joomla, typical acceleration is about 100 times.

Joomla doesn't make using Varnish easy, though. By default not only does it send headers that forbid caching, but also starts a session for every anonymous user. While the former is fixable using multiple freely-available plugins, the latter is an issue with the Joomla core.

MassiveScale.net has developed a patch for the Joomla core and a Varnish VCL file which work together to serve anonymous traffic from super-fast Varnish cache, while still allowing users to log in, bypassing cache. They are accompanied by a content plugin, deleting articles from Varnish cache as soon as you save them.

Some numbers

We did a little test: we took a sample Joomla 1.5 page and load tested it using Apache Benchmark. 10000 requests have been sent, with 20 concurrent connections. The load generator has been running on the same machine as the web server - this is not the most precise test setup, but still it gives some insight into how load times relate to each other.

The results are two orders of magnitude (~100 times) better with Varnish than without it. Also, while a test without Varnish was running, load was high on the test machine. With Varnish it was close to nothing.

FAQ

What is included in $70 package?

Patches for Joomla 1.5, 2.5.4+, 3.0, 3.1, 3.2, 3.3, VCL files for Varnish 2.1+ and 3.x, a plugin purging articles from cache (for Joomla 2.5 or higher), and 12 pages of documentation in PDF, ODT and TXT. We also add 30 minutes of support, including installation.

Will it help my e-commerce site?

Most trafic on e-commerce sites is coming from anonymous users, who just look at things without creating an account or buying anything. Varnish will help you.

Couldn't you just make it a plugin?

No, we couldn't. According to our best knowledge, there is no way a plugin can be used to bypass creating a new Joomla session. We'd be happy to be proven wrong, as patching is not the nicest solution in the world.

What are the requirements?

A supported Joomla version and root access to your server (that is, you need a VPS or dedicated server, not a hosting account).

If your hosting doesn't meet these requirements, check our offer.

What was your exact test setup?

The machine was a quad-core PC with 4GB RAM and a 7200 SATA drive. It was running versions of Apache, PHP, MySQL and Varnish found in Ubuntu 11.04. The software configuration was out-of-the-box, it hadn't been tuned for performance. Joomla 1.5.23 was used with a default set of sample data.

What about 1.6/1.7/2.5.3?

These versions are unsupported. There are patches for these versions in our package, but we don't update them anymore. Both of them are at version 1.1. If you really need to upgrade them, we can do it for the standard hourly fee.

Which extensions are supported?

Most well-written extensions work well with Varnish without any extra work. The most popular ones include JomSocial*, Akeeba Backup, Admin Tools, Kunena and HikaShop. Community Builder and VirtueMart work too, although sometimes a little tuning may be necessary.

* JomSocial Ajax Notifications are not supported

Which extensions are known to cause a conflict?

K2 (which is trying to support Varnish, but is doing it wrong)

What Varnish versions are supported?

All versions from 2.1 up. We provide two separate VCL files - for 2.x and 3.x (but please upgrade to 3.x, really).

Can I try before I buy?

We have a sample optimized Joomla! website put online at http://joomla.varnishdemo.mvps.eu/. You can just browse this page or you can run some load testing tools against it. Try Apache Benchmark: ab -n 2000 -c 50 http://joomla.varnishdemo.mvps.eu and observe system load.

What payment options are available?

Paypal and credit cards when ordering online (order now). Bank transfer, Payoneer, and Bitcoin are available after contacting us.
