Fastruby 0.0.21: Inline of corelib fixnum methods, restored ruby 1.8 compat

Fastruby is a gem which allows to execute ruby code much faster than normal, currently in a state of transition between a spike and a usable gem, it is released when possible with incremental improvements.

One of the main improvements on fastruby v0.0.20 v0.0.21 was the implementation of a few corelib methods (e.g. Fixnum#+) in ruby to allow inline them. The other is the restored compatibility with ruby 1.8

Install

You can clone the repository at github:

git clone git://github.com/tario/fastruby.git

git checkout v0.0.21

Or install it using gem install:

gem install fastruby

Speedup

Before (v0.0.19 and prior)

Now:

NOTE: Since issues with 1.8 compatibility, inline of corelib methods won't works on ruby 1.8, this will be fixed for v0.0.22 in future releases

Next

• Improve speed of dynamic call lookups (not direct or inlined calls)
• Inline of inherited methods and potential inline (when a new method is defined methods calling it will be recompiled in order to inline)
• Parallel build of methods

Fastruby 0.0.19 released: improve of inline, performance bugs fixed

Fastruby is a gem which allows to execute ruby code much faster than normal, currently in a state of transition between a spike and a usable gem, it is released when possible with incremental improvements.

The main improvements on fastruby v0.0.19 are refinements on the inliner algorithm:

• Inline of block calls (was not possible before)
• Inline of methods with block calls (was not possible before)

And the fix of two important bugs:

• Duplicated entries on $LOAD_PATH creates an incremental latency on require as new methods are built. Fixing this bug allows obtaining a reduction of total time of tests of %80 (150 seconds to 30 seconds on my machine). Moral: don't touch $LOAD_PATH if possible
• Replacement of CFUNC calls using the previously implemented observer mechanism for inlining
• Fixed case statements reduction to use deterministic names for temporal variable and allow caching of methods using case statements

No new big features...
