Ruby Performance Patches

There are several ruby performance patches, like the falcon patches, that may improve the performace of your application.

I use rvm and was pleased to learn that rvm supports compiling ruby with several of these performance patches. Using rvm with the railsexpress patch, I saw a 20% reduction in the time required to run the test suite for a large rails project.

Here is how you can install ruby with the railexpress patch using rvm.

First make sure you have the latest version of rvm.

1

rvm get head

Next install ruby 1.9.3 with the railsexpress patch. At this step rvm may have dependencies that require installation.

1

rvm install 1.9.3 --patch railsexpress

The railsexpress patch contains the following patches.
