Editor Slow !! ??

Hi,

I'm using build 3461 on Windows XP. Dell Precision 650, 2 GB RAM, Dual
2.66 GHz Xeon processors.

Occasionally IntelliJ 4.5 would be a bit slow. However build 3461 is
ALMOST UNUSABLE. It can never keep up with my typing. I need to keep
pausing and waiting for it to catch up.

Anyone else having same problem?

Any configurations that can be changed?

These are my current idea.exe.vmoptions settings:

-Xms128m
-Xmx512m
-XX:MaxPermSize=92m
-ea

I've got no hints, but I also find that 5.0 seems much slower than 4.5.3

I am on a Dual 2.8 Ghz Xeon with 2GB Ram, XP SP2 and it runs very well.
It may have something related to what you are working on that is slowing
down IntelliJ. There are instructions in previous posts on how to add a
port number to some file to enable the ability to take a CPU recording.
You click it to start the recording, then you click it again to end the
recording.

Anybody remember what that is?

I use IDEA (standard config) on a single CPU 2,4GHz machine with 1GB RAM and
find its speed OK - even on the Mac mini. But I always used the EAP builds,
so I might be a little bit accustomed to the slowness...

I've noticed that the performance (at least under Linux) is strongly related to the look and feel that you are using. The new alloy look and feels are pretty much unusable, while metal seems to be the fastest. I don't know if this is a java issue, an intellij issue or an X11/nvidia issue but, depending on what look and feel is being used, you can see a huge difference in the amount of cpu that X is chewing.

An known slow down is also the "Show structure" of the project panel.
Editing Swing-components (especially pressing enter), causes a major
slow down when the structure is shown.

Thanks for the tip,

I was using one of the alloy L&F's. I've switched back to IDEA 4.5 L&F
and it does seem somewhat better, not great though.

Hmmm. That's interesting. I almost always have the structure window
open and I don't see any problems. Maybe it's the CPU power that I have?

Show off :) Get a real machine and then work with us little single CPU
people.

Hi,

I added empty ejb module to my project and suddenly IDEA starts working extremely slow... I think current slowness in 5.0 is because of this module.

Try to remove this module. At least you can use IDEA as excellent editor. Will wait for fixes.

I am working in an EJB project with the Structure view open and I don't
have any problems. In fact, I see very little CPU activity.

Bring up the taskmanger (CtrlShiftEsc on a wintel), then minimize it to system tray.
Start editing problem files, then look to task manager indicator when slowness begins. Is CPU(s) load is 100% ?
In my case this always take place when IDEA starts checking file syntax (look to analysis indicator). When file is as large as 1500-2000 lines of text, the IDEA becomes slow on my weak machine. When file is as large as 5000 lines of code, IDEA becomes simply totally unusable, even when all errors checking turned off to "Do not show", and even when reparse delay is increased to 2-3 sec.

...I thnik IDEA programmers should rearrange threads priority. The user should have absolute maximum proprity. (Not system/service tasks... )
