Idea's performance

Hi All,

I am having major performance problem when Idea loads for the first time or when it wants to shutdown. I'm also getting exceptions when I build my modules externally (using maven). this problem started to happen since build #5175.
By the way, it's not a hardware problem as my hardware hasn't changed since older versions, and it's quite a good system (Cpu 1.8Ghz, 2.5GB ram, 80GB hard).

Has anyone nothice the same thing?

I'm using the latest build ( #5368 ) and I am still noticing these performance issues. We have a large project and it is very slow to open. It parses the files every time and no longer seems to cache them. Also when you exit IDEA locks up for a couple of minutes while I guess it's doing cleanup. Seem an awful long time just to quit a program...

I don't have these issues in 5.1.

Do you get any exceptions while opening or closing the project? If everything
works correctly, you should not see any parsing going on while the project
is being opened.

Oh, while we're on the subject, I'm getting tons of exceptions while opening a project in the latest couple builds. 11 of them to be exact, all of them reading "Repository caches are corrupted and will be rebuilt on the next startup". It doesn't matter how many times I restart IDEA; even completely wiping the caches doesn't help. Yeah, that also happens without any third-party plugins installed. Yeah, they've been reported to the tracker.

I did get an exception closing the project. A stack overflow I think. I reported it.

However on opening the project I don't see an error. As a crude test I opened our project in 5.1 and Demetra. I opened the project twice in each one to ensure caches were up to date. Here were my results:

Opening project in 5.1 -


17 secs.
Opening project in build 5368 -


1 min, 19 secs

I would like to point out we have an insanely huge project. 10,000+ class files and thousands of jsp and resource files.

Also, once the project is open performance seems fine...

It would be a great help for is if you could take a CPU snapshot of the project
opening.

I (think) I uploaded it. I used an FTP client that I'm unfamiliar with. I also don't know if the folder has read or only write privledges. Let me know if it didn't make it and I'll try again.

We have received the snapshot correctly, thanks. We'll investigate it to
see what can be done to improve the performance.

Y'see this is why I pay for this thing year in, year out.

I try to explain that to people and they just don't get it .... :(
