One interesting question however: Has anyone measured if Squid benefits from NPTL (and NGPTL), or if it prefers the old LinuxThreads model? The use of threads in Squid is rather different from most other applications using threads, so it should not be assumed what is generally better is also better for Squid. I have not done any such measurements as we are still using stock Linux kernels without the NPTL extension, but it would be really interesting to know. I think you can have a RH9/FC1 system run the same binary with either by just setting a LD environment variable. Regards Henrik
