comparing ruby 1.9 performance on ec2

benchmarked using ruby's benchmarking suite. all machine are brand new fedora 8 basic instances, not running any additional services. all tests done on ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux] compiled from source with --enable-shared flag. benchmarks performed twice on 2 separate instances.

results speak for themselves, don't forget to compare ec2 pricing ;)
