[ANN] 1.9.3-p0 proof-of-concept available for testing
Jon
The purpose of this proof-of-concept is to see if we're on the right track for fixing MRI's 1.9.x performance regressions on Windows. Currently we believe three areas are ripe for improvement: `require` behavior, api selection, and IO/Encoding optimizations. This download implements initial source code modifications for all three categories.
Potentially the most problematic is that we've set the default IO mode to O_BINARY. Problematic because it is likely to cause problems when interacting with "\r\n" delimited files. As such, this is not really "the fix" and simply allow us to see how optimizations in the IO subsection *might* work to solve the dramatic slowdown benchmarked and discussed in these two posts:

Caveat emptor.
With that in mind, strap on a helmet and test in a variety of Windows environments (XP SP3 or higher). We'd like to hear what works and what breaks. We'd especially like to hear how it performs and whether it's noticably faster for you.
Specifically, we're interested in feedback from the following areas:
* Rails
* BDD/TDD (cucumber, rspec, minitest)
* GUI (gtk2 and tcl/tk)
* XML and other file/data munging apps

Build and optimization summary:
* Built via RubyInstaller recipes using TDM GCC 4.5.2 DevKit
* Uses MRI's `ruby_1_9_3` source branch with these patches:
* Dušan's `dmajkic/ruby_1_9_3` branch containing:
* faster winnt_stat and O_BINARY as default
* Yura's `load.c` patch for sorted $LOADED_FEATURES
* Tweaked `version.h` to ease usage with pik
* RUBY_DESCRIPTION add "tcs" to allow `pik 193 tcs` to switch
Thanks,
Jon
