Then your system is too heavily loaded for your satisfaction. You need to use system monitoring tools (sar, vmstat, iostats, procinfo) to see where your system is bottlenecking, and then correct the problem. The best place for help from this point (since it isn't really a Squid problem) is a mailing list for your OS - if you have further questions/problems, ask there. Adam
