NetBeans Performance
Welcome to old NetBeans Performance Team's site. Redirecting to wiki...
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.
