NetBeans Performance

Welcome to NetBeans Performance Team's site.

You can find various information related to computational performance, startup time, memory footprint, perceived performance (UI responsiveness) and scalability of NetBeans IDE here. If you are interested in specific information you did not find here, let us know on nbusers@netbeans.org mailing list. Don't forget to put the keyword "performance" in the mail subject. Let us also know if you want to help make NetBeans performance better. We would definitely appreciate if community members would like to work with us.

Quick tips:

• Frequently Asked Questions
• Tuning NetBeans performance with JVM switches

To see what we are doing for improving NetBeans performance, go to our wiki pages:

• NetBeans Fitness Program - home page for NB performance improvements in progress
• Performance Improvements in NetBeans 6.1 - summary of improvements in the latest release
• Performance work for NetBeans 6.1 - home page of performance work done for NB 6.1
