This is a theoretical benchmark of require time comparing ruby 1.9.4 r33453 original and patched on a 64-bit Linux with a sequential hard disk.

It is theoretical because it is based on requiring a few hundreds empty files from the same folder, which is likely rare.

However, the global result (patched significantly faster than original) should be reflected in a certain measure in real life.

It is showing especially good results, because a file is never required twice, and so the unpatched version always has to check every file loaded.

The patched version could actually be slower when:

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
