Weblogic slow with Eclipse breakpoints

Question

Sometimes when I use Eclipse with breakpoints set, the performance of my Weblogic is very slow. Any ideas?

The performance is slow in general - it isn't only slow when breakpoints are hit.

I'm debugging with a Weblogic on my local machine.

When I disable all breakpoints everything instantly speeds up.

I don't always have this problem. Not sure why it sometimes happens.

I'm using Eclipse 3.2.2 with the 1.0.11 of the Forthnet Eclipse WL plugin.

Update: This appears to be due to using method breakpoints (ie: break on method start/exit). Not sure why this is the case but the problem comes and goes depending on whether I have method breakpoints set.

Answer 1

Check you heap usage...at least it use to be that debugging used lots of heap and the slow down was due to GC running. Removing all the break-points might allow the memory to be re-claimed.

A couple of releases back (in the old Workshop, pre-Eclipse) you would have to limit a debug session to 2 - 3 hrs before needing to restarting the server.
