Painfully Fast (Now)

Today the debug team revels in its own greatness...Ok we didn't actually fix anything, but we did find out that a bug that was a critical stop ship for us was not at all our fault AND someone had already fixed it (I love those ones).

The bug in question is https://bugs.eclipse.org/bugs/show_bug.cgi?id=153458, and long story short, has to do with the apparent 'extreme slow down' of the eclipse debuger. It turns out (as the previous comment dictates) that it was not our fault; it was really a combination of factors...but mainly the new conjestion algorithm in the newer Linux kernels (> 2.6.14). Luckily though the kernel champions jumped on it and bullied Sun into fixing the way jvms communicate over TCP/IP.

To summarize:
If you have a newer Linux kernel (> 2.6.14) and you are NOT using jdk 1.5.08 or jdk 1.6 r79 you are boned, and doomed to have a matrix-neo-style debugging experience.
