Have you noticed your Eclipse Debugger getting slower and slower over time?  I noticed moreso with my Mac, so I found this posting by Dave Kelsey, so hopefully it helps you out…

It looks like the leak and performance hit is due to the use of the Debug Output View.
If you disable sending information to this then I think you won't see the performance hit. To disable these outputs go to
Window-->Preferences
Expand PHP then Expand Debug
Select Installed Debuggers
Double Click on XDebug
change Capture StdOut and StdErr to Off
click Ok.
