There are some reports of performance issues on 3.5 ... Here is the data I've gathered so far:

"java editor
657 line file (with quite a few errors in it, just for good measure)

holding down the arrow key to scroll through the document:

eclipse 3.5.0 carbon 32bit leopard JDK 1.5 = 24s
eclipse 3.5.0 cocoa 64bit leopard  JDK 1.6 = 61s
eclipse 3.5.0 cocoa 32bit leopard  JDK 1.5 = 71s
eclipse 3.4.2 carbon 32bit leopard  JDK 1.5 = 21s

this basically is showing that it's not 1.6 vs 1.5 (though that DOES give a decent bump to be on 1.6), but instead it's cocoa vs carbon making the big diff

it appears that there is some degenerative redraw bug being hit here. maybe it's related to the package explorer scroll bug too?"

this is tracked in https://bugs.eclipse.org/bugs/show_bug.cgi?id=282229
and to some extent in https://bugs.eclipse.org/bugs/show_bug.cgi?id=268877

I haven't done testing of WOLips under 3.5 carbon, but I'm going to switch back to it and check it out, because it appears to be substantially faster than 3.5 cocoa in this particular build. I'm sure this will be resolved in 3.5.1 (iirc 3.4.0 was a bit of a disaster as well).

I find that if I highlight a number of files and F3 it's a disaster... the game's pretty much over :-/ No idea yet what the cause is.
define "game's pretty much over" -- total app crash? deadlock? exception?

Wait for 15 minutes whilst the beachball's at play and it may/may not open the selected files in that time. I find that the more files I open the slower 3.5 gets. I have to close lots of files to get back to normal operating speed.

I went back to 3.4 due to the very noticeable slowdown, especially with a number of open files. For me, 3.4 definitely feels a lot more responsive.

cheers, Fabian
