Upper limit on concurrent connections?

Hi,

Does anyone have experience of Squid running with large numbers of
concurrent client connections? Our caches are regularly seeing 1000 - 1500
concurrent connections and have around 4000 FDs in use. These numbers are
increasing with time as our user base grows. We're running Squid 1.1.22
under Linux with the filehandle patch. I can continue to increase the
appropriate limits, but is there a practical limit to the number of
concurrent connections before performance starts to suffer (given that disk
I/O isn't a bottleneck)?

Thanks,
Simon.
