Chuck Remes created JRUBY-6285:
----------------------------------
Summary: JRuby 1.7 master on Java7u2 is *slower* running a
benchmark than master on Java6
Key: JRUBY-6285
URL: https://jira.codehaus.org/browse/JRUBY-6285
Project: JRuby
Issue Type: Bug
Components: Performance
Affects Versions: JRuby 1.7
Environment: OSX apple-provided java6, openjdk java7, jruby 17 master
Reporter: Chuck Remes
1. Run the install_me in this file.
http://dl.dropbox.com/u/44434337/jruby_perf.tgz
2. cd rzmq_brokers-0.7.1/test
3. jruby --server test_consensus 5555
Here are my results from running master with java6 and java7.
https://gist.github.com/1491345
The java6 results are significantly better than the java7 results. This tells
me two things. One, that jruby master has some excellent code improvements.
Two, somehow java7 is not optimizing those as well as it should.
