I don't intend to patch ruby for rails - rails 2 and rails 3 use the same ruby version.

Maybe you should give it a try... The patch we use is this one: https://github.com/patshaughnessy/ruby187gc which is a port from ruby186gc.patch from https://github.com/skaes/railsbench. There is also a ruby 1.9 version available. For Studio the performance increase was huge, ~30-50% on susestudio.com and 50% for the test suite.
