I've done all the common stuff: recompiled the kernel and stripped out unused drivers strip -s kernel file maxusers -> 256 net.inet.tcp.recvspace=65535 net.inet.tcp.sendspace=65535 kern.ipc.somaxconn=1024 But I'm wondering if there are other areas (such as hard drive r/w buffers in the kernel and/or memory allocation) that can be readily increased that will have a positive impact which I am over looking. Any other areas I should be looking at and/or any ideas? Thanks! Ray
