Yes, you could see the difference with big projects with change in settings as descibed here:

Does this happen frequently/consistenly for you? I have seen this kind of slowness you are describing. We would appreciate a thread dump when this happens with machine config and IDE log.

Sakthi,

I finally got a chance to revisit this problem. Sorry for the delay. Yes, the CSS typing lag happens frequently. If you open the project with no pages open then the CSS editor is fast, but once you start opening pages it slows down, especially if those pages have a lot of components. I opened up one page with about 150 components and another with 90 and now every time I type a couple of characters into the CSS editor it hangs for about 8 seconds (I counted). Closing the pages does not help either, I have to restart NetBeans to make it fast again. I tried to recreate this in a brand new project and was unable to. Maybe it has something to do with my project being fairly large (65+ pages)? I've included the thread dump below. When I took this thread dump I had 6 pages open, I then typed 揳aaaaaaaaaa?into the editor and then it hung for 39 seconds. Nothing was added to the IDE log during this delay.

Also, other than the CSS editor and opening pages, I've seen significant slowness when changing the id on components. In Creator, this used to take under a second. Now, it takes between 8-15 seconds regardless of the size of the page. Is it scanning the entire project for places where it needs to rename the component?

My computer is a Dell GX620 w/ P4 3.2Ghz (HT Enabled), 2GB RAM running XP SP2
