I recently upgraded a Soekris 4801 firewall from OpenBSD 3.7 to 4.0. The configuration for firewalling (pf.conf) is unchanged. On 3.7, at peak throughput I normally saw maybe 65% - 76% interrupt mode and little or no congestion. However, on 4.0 with similar traffic levels I see 85% - 95% interrupt mode and the congestion counter increments fairly rapidly.
Of course, one cannot expect best performance from a Soekris due to the Ethernet chipsets, but it was -adequate- on 3.7. I've spent a little time google'ing for any observations on a difference in performance between 3.7 and 4.0 and have found nothing useful so far. Have other list members had this experience or know of anyone else who has? If so, has anyone had any favorable performance tuning experiences that might help me out? So far, the only tuning change I've made for 4.0 was to increase net.inet.ip.ifq.maxlen from 50 to 150, but this appears to have had negligible impact.
