Bad performance calling Java classes
------------------------------------
Key: JRUBY-2803
URL: http://jira.codehaus.org/browse/JRUBY-2803
Project: JRuby
Issue Type: Improvement
Components: Java Integration
Affects Versions: JRuby 1.1.2
Environment: Fedora 9, Sun Java 1.6.0_06, SWT 3.4
Reporter: Uwe Kubosch
Attachments: top_ticker.tgz
Small project attached.
In implementing a ticker for the desktop notification area, I get decent
performance using a Java class to call the Java SWT API, but very low
performance using a Ruby class calling the Java SWT API.
Run with
jruby top_ticker.rb
uncomment line 12 and comment line 13 to switch to Java.
Calling Java APIs is core functionality for our project and I hope you can find
a way to speed this up.
