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.
