Ruby 1.8.7 enable-pthread for performance improvement

Solution Unverified - Updated -

Issue

It is well known enable-pthread option is causing slowness in Ruby 1.8.7. In Ruby enterprise edition, it uses disable-pthread, and in ruby version rolled out by puppet for puppet enterprise 2.0 for RHEL6, it also uses disable-pthread. In Ubuntu/Oneiric 11.10, this issue is resolved, it uses "ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]".

In RHEL6U2 (ruby-1.8.7.352-3.el6.x86_64) and Fedora 16 (ruby-1.8.7.352-3.el6.x86_64), the enable-pthread is still in place, causing slowness.
