I found=20 kern.polling.idle_poll=3D1 to improve performance in polling. Also, try updating the box to 6.2 first as there are quite a few improvements to the em driver You can also fiddle with assigning less to userspace with=20 kern.polling.user_frac=3D30 Don remember for sure, but ipfw seemed to be a bit faster that pf. Also with no firewall loaded there seemed to be quite a bit more throughput... However, that kind of defeats the purpose of a firewall. Also, did you try without polling in the kernel ? The way the updated em driver works should negate the need for kernel polling as well. Also if you dont use INET6 or ipsec, I would remove them from the kernel ---Mike -------------------------------------------------------- Mike Tancsa, Sentex communications http://www.sentex.net Providing Internet Access since 1994 mike@sentex.net, (http://www.tancsa.com)
