I am happy to report that 3431 now feels as fast as 4.5.x.
LOL I guess I shouldn't be too excited since it just meets and
doesn't improve upon 4.5.x, but from where we came from in
earlier builds, this is a major improvement.
Qualitatively, I find doing operations like copy&paste,
insert newlines, etc. feels about the same as 4.5.x now.
Quantitatively, I did some tests like hold down on ENTER
key for 5 seconds to see how many newlines IDEA would
insert (160) and to see if there was any chunky updates or
large delays after the operation. I also pressed UNDO key
for 5 seconds to undo those changes. I then copied some
code and repeatedly pasted it by holding down PASTE key.
Both 4.5.x and Irida performed almost exactly the same.
Both are able to keep pace with my keyboard repeat rate.
Irida no longer has chunky updates or long pauses after the
operation is over.
All tests performed on a P4 2.8 Ghz / 1 GB / WinXp Pro SP2.
Keyboard repeat delay set to Shortest and repeat rate set to
Fastest in windows control panel.
