I stand corrected. I had run benchmarks in the past which indicated that NPTL was not being used. I just reran the benchmarks, and I appear to be quite wrong. I also checked with lsof, and sure enough the JVM is linking with the NPTL libraries (unless you set LD_ASSUME_KERNEL to 2.4.1). I did some searching on bugtrack and found Bug ID #4802778, which indicates that the JVM has not been tuned for NPTL, but currently does use it, and that the LinuxThreads work arounds in the JVM proved to be benign. So, now I know what I'll be doing tomorrow: trying to figure out why the benchmarks indicated otherwise when I tested this a few months ago. :-( --Chris ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
