Compile-and-run settings that speed up bignum-intensive apps
Applications that employ combinatorial methods frequently need to make huge numbers of calculations involving JRuby bignums. Such applications should benefit from the following compile-and-run settings:
jruby -J-server -J-Djruby.compile.fastest=true foo.rb
jruby -J-server -J-Djruby.compile.fastest=true -J-XX:+UseParallelGC foo.rb
Has anyone found other settings that help ?
