Java 5/6: Java thread priority problem and workaround
Endre Stølsvik has very detailed research and explanation along with workaround to a problem of broken thread priorities in linux in his blog:
Linux Java Thread Priorities workaround
The kind of situation when you'd like to have priority changed is accepting socket thread under high load (or, of course, a DoS attack ;-) ), or GUI dispatch thread.
BTW, my opinion for running java server-side is strictly solaris-based server, if you can afford it. At least you won't have OS LWP creation overhead for each java thread you start.
I had never tried opensolaris for java deployment, but it seems like just a different build of same beast. Did you?
