compiler performance problem [message #79353]

eclipse 2.1.1

We are experiencing performance problems with the Java Compiler.
Our project is on a remote unix and connected via samba.
We turned off Auto Build.

All our Jars are local, we have ONE 4500 line class in the project.
Compiling this class takes up to : 51 seconds !!!!
a non-op save (add a space) takes more then 10 seconds !!!

I turned on the debug and attached a log. It seems that the class is being
compiled even though no changes where performed

Do you have any idea how to boost performance?? this is WAY too long

Thanks

Eli

development teams go through all kinds of hoops to try and get around this
problem. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=10628 and

Hi Ed,
We have 3 files on the remote unix: .project .classpath and one .java file.
All the external jars and rt are local.
performing a no-op action rebuilds all the .class files. Is this supposd
to be this way?
I patched https://bugs.eclipse.org/bugs/show_bug.cgi?id=40174 and things
are working a bit better.

this still seems to take too long.

The bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=10628 is open for
over an year and it was not addressed in 2.1 (although, if I don't
mistake, performance was one of the main targets of 2.1)
I must add that performance over DFS is terrible as well.

For best performance make sure the project directory itself, the workspace,
and the .metadata directory are on the local drive as well. You can try a
system monitor tool like filemon at www.sysinternals.com (free) to check
for any hidden accesses to network files. Local file access can be greatly
affected by a fragmented hard drive so a defrag could help a lot too. I've
done all these things and I've see a 10x - 100x performance difference on
builds and refactorings. It's unfortunate that you have to make a tradeoff
between performance and the security of using networked, backed-up storage,
and it would be nice if this could be addressed in a future release.

I have been having some problems with the newsgroup,
but anyway, I made the whole project local and it still takes 10 seconds to
compile a no-op operation!
Disks are fragmented.
Any ideas?

Sounds like you've done all you can without breaking out a profiler and

that is exposing a compiler issue. In the meantime all I can suggest is that
you can turn off automatic rebuilds in the prefernces and do builds only
when necessary. HTH.
