Description kawazu428 2009-06-17 07:57:38 UTC

(filing to "ide" again, still missing something like "performance", "usability", ... in issuetracker components)

Using recent IDE builds, despite some of the scanning-related issues seems to have been fixed, overally at least making
the IDE start up faster, at the moment I am sad to see that NetBeans is next to unusable in my environment (>50 maven2
projects in a "folder-of-projects" group). 

Experiences:

- IDE starts up pretty quickly now. Good.
- As soon as it is up however, I frequently am presented a notification box showing something like "System slowness
detected, system unresponsive for XXXX ms" (XXXX usually > 1.000, most of the time > 2.000). Attaching a profiler
snapshot, showing that obviously(?) CLI Requests Server is causing this kind of trouble?
- Generally, the IDE by then is next to unusable. This message pops up, like, a dozen times in a minute, and the IDE
seems to be somewhere in betweeen showing this message, being "unresponsive" (in terms of the UI not being repainted)
or, for a few couple of seconds, actually accepting user input.

Not really pleasant at the moment, unfortunately. Any more input I can provide on this? It generally seems that NetBeans
so far has severe problems with larger project collections opened...

Looking at the NPS file, it seems that the AWT thread is blocked for 3s while opening options dialog. As this is 
usually lengthy operation, I'd suggest use of progress bar while the categories are initialized in background.

Comment 4 kawazu428 2009-06-17 10:05:39 UTC

Well... I don't completely remember whether I was opening "Options" dialog during that very session, but the behaviour
is the same also if doing a "clean" IDE start and just doing work in open file editors restored from the last session.
So I'm not sure whether this only relates to the "Options" dialog after all...

I reassigned the bug based on the content of your nps file.

WAIT_CURSOR is shown when opening Options and when switching between categories. It takes some time to initialize panels.
