You could try adding/tweaking HZ to 1000/2000 in kernel and add kern.polling.enable=1 to /etc/sysctl.conf. > Nov 18 04:00:15 d thttpd[38743]: write - Socket is > not connected > sending /path/to/file.name > Try adding: kern.ipc.somaxconn=2048 kern.maxfiles=65536 net.isr.enable=1 to /etc/sysctl.conf as well. net.isr.enable gave better network-performance on a 5.3 RC3 nfs-server and lower cpu-usage.
