Key: JRUBY-6082
URL: https://jira.codehaus.org/browse/JRUBY-6082
Project: JRuby
Issue Type: Improvement
Components: Core Classes/Modules, Interpreter
Affects Versions: JRuby 1.6.4
Reporter: Thomas E Enebo
format/% should cache parsed format strings to avoid successive parses.
Most uses of format happen in a loop and it seems a shame to constantly reparse
what is generally a static format string.
This is more of a captured idea than a known perf problem. Someone should run
a typical Rails app and see how often format is being executed.
