RACK works for me: net.inet.tcp.functions_available: Stack D Alias PCB count freebsd freebsd 0 rack * rack 23 I don't see any lags when starting/using FireFox or any other browser. Mail delivery (in/out) is also not affected. But GENERIC, which is loaded by GENERIC-NODEBUG, doesn't support RACK. These entries are missing in GENERIC: makeoptions WITH_EXTRA_TCP_STACKS=1 options TCPHPTS options TCP_RACK -- Gary Jennejohn
