IDEA 5.1 debugs very slowly

I just upgraded to IDEA 5.1, and the debugger has become very slow. What I mean by this is that if step through a program (Step Into, Step Over, etc), it can take IDEA 1 to 5 seconds to finish each step operation. Moreover, if I attempt to expand a variable in the "Frame" tab, it takes around 5 seconds for IDEA to respond. During this time IDEA is not using any CPU. In fact, my CPU sits idle the entire time I'm waiting.
Is this a known issue? I should add that I'm not sure if this is due to my upgrade to 5.1, as I also upgraded to a new box at the same time and am now running a dual core AMD processor. Here is some system info:
JDK: Sun 1.5.0_06 (this is the JDK being used by my project)
Operating system: Linux (Ubuntu)
Kernel version: 2.6.15 (PREEMPT "k7" kernel from Ubuntu distribution).

Any ideas?


I am running Java 1.5.0_06 on Mac OS X 10.4.6. After I upgraded to 5.1, my debugging too has become unusably slow. I have checked everything, and I even upgraded my memory on my powerbook G4 (1.5Ghz) to 2Gb. Nothing seems to help. I used Ethereal to look at the packets on lo0 (localhost) and there are thousands of packets that say there was a checksum error. Any ideas (no pun intended)? I do not see this problem on my Quad Power Macintosh (same operating system).

I should have said 5.1.1 in the last post.
