Annoying "Remote System Explorer Operation" causing freeze for couple of seconds

Question

I observe "Remote System Explorer Operation" in Progress view of Eclipse after each save of Java file (so it might be related to compiling?). It makes the Eclipse unusable for 1 to 10 seconds. In some projects (of about the same size) it's quicker, in some it's slower.

I have no idea which plugin might be the cause for it. I have Build id: 20090920-1017. I have quite a few plugins installed.

I have tried turning all the remote systems to enabled=false under Preferences | Remote Systems (whatever it means). I didn't help.

Any idea how to solve it?

EDIT:

1. It doesn't happen when Project | Build automatically is turned off. So it's some part of the building process.

Answer 1

Smells like it's in this:

That's probably part of the JEE stuff. Not sure how to turn it off though.

Answer 2

The issue disappeared after some update of the Eclipse libraries (still using the same build). So I guess the solution is to perform an update.
