This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
The users often complain that NetBeans is sluggish. This is often considered a performance problem which is not correct. What the users care about is the perceived performance, not raw numbers. We need to review all frequent UI actions and make sure they are responsive enough. In many cases what we need is to change the way NetBeans responds to the user action, not necessarily to make the current way faster. Sure in some cases an optimized code is needed too. The work must be done in the platform as well as in modules.
The most irritating "slow response", especially for me who is used to Kate (text editor in Linux KDE3) and has had me shy away from NB, IS; Opening a java class that starts the Form Editor. First time is killing (15sec) but subsequent opens are just as annoying.

These issues are planned as Sun's "must have" contribution to NetBeans 4.0 and are considered to be "high level" issues. That is why changing the type to FEATURE and priority to P1.

Mostly done, I guess. At least it is completed enough to claim success, isn't?
