I have rebuid the FreeBSD 5.3-RELEASE kernel with options below: options DEVICE_POLLING options HZ=1000 on ThinkPad iSeries 1800. And setting 'sysctl kern.polling.enable=1', then running dnetc installed from ports(dnetc-2.9008.491_1,1), I detected considerable amount of packet loss. Top command shows that dnetc is using 1000% (not 100%, but 1000%!). ping result (snip) 64 bytes from 192.168.2.200: icmp_seq=258 ttl=64 time=9597.83 ms 64 bytes from 192.168.2.200: icmp_seq=268 ttl=64 time=9624.56 ms 64 bytes from 192.168.2.200: icmp_seq=278 ttl=64 time=9612.66 ms 64 bytes from 192.168.2.200: icmp_seq=288 ttl=64 time=9639.19 ms 64 bytes from 192.168.2.200: icmp_seq=298 ttl=64 time=19652 ms 64 bytes from 192.168.2.200: icmp_seq=318 ttl=64 time=9579.19 ms 64 bytes from 192.168.2.200: icmp_seq=328 ttl=64 time=9606.89 ms 64 bytes from 192.168.2.200: icmp_seq=329 ttl=64 time=8606.83 ms 64 bytes from 192.168.2.200: icmp_seq=338 ttl=64 time=19564.4 ms 64 bytes from 192.168.2.200: icmp_seq=340 ttl=64 time=17564.2 ms 64 bytes from 192.168.2.200: icmp_seq=358 ttl=64 time=9547.07 ms 64 bytes from 192.168.2.200: icmp_seq=361 ttl=64 time=6546.53 ms ^C --- 192.168.2.200 ping statistics --- 372 packets transmitted, 201 packets received, 45% packet loss round-trip min/avg/max = 0.367/1158.48/19652 ms top result PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 434 dnetc 139 20 964K 764K RUN 11:09 1259.46% 1259.42% dnetc Is this the problem with polling? Please let me know. Thank you.
