I've checked out the code. I think it was about 50 MB. I did not
encounter any problems. ..

One thing that occurs to me, as others have had problems like this in
the past ... are you running builds outside of Eclipse, such as using
Ant? This can cause performance problems as the build creates a ton
of new files that Eclipse does not know about. When the workspace
refreshes and it discovers them it sends a flood of resource changes
through the system and it can take a while to process all of those.
We've done most of the optimizations we can, I actually thought the
problem was resolved as I do not recall hearing it lately. I am just
speculating anyway since I am not seeing a problem. So just trying to
think what else we could look for.

Thanks for investigating this Mark. (Sorry for late reply, had some
trouble sending via Nabble.)

Yes, I did run the Scala Ant build outside Eclipse prior to seeing
this behavior.

It may well be some kind of rare sickness specific to my local
environment. Other Scala users are not reporting the problem. And I
notice that the methods taking most of the execute time are all native
methods, so its seemingly not the Java code that's "at fault".

There's one thing about my case that's unusual: Im running in PDE
launch mode, ie Eclipse launched from Eclipse. No idea if/how that
might affect low-level SVN performance though.
