I = try with netio and TCP. The used Nics are onboard Broadcom=20 (PCI-X133Mhz), an Broadcom PCI-X Nic and an intel PCI-X Nic. The CPU=20 load is around 35% and the performance like this: Packet size 1k bytes: 99303 KByte/s Tx, 44576 KByte/s Rx. Packet size 2k bytes: 72043 KByte/s Tx, 75200 KByte/s Rx. Packet size 4k bytes: 23280 KByte/s Tx, 66072 KByte/s Rx. Packet size 8k bytes: 55234 KByte/s Tx, 64470 KByte/s Rx. Packet size 16k bytes: 82485 KByte/s Tx, 74099 KByte/s Rx. Packet size 32k bytes: 93133 KByte/s Tx, 74992 KByte/s Rx. I try the following tuning: kern.ipc.maxsockbuf=3D16777216 net.inet.tcp.sendbuf_max=3D16777216 net.inet.tcp.recvbuf_max=3D16777216 net.inet.tcp.sendbuf_inc=3D16384 net.inet.tcp.recvbuf_inc=3D524288 net.inet.tcp.inflight.enable=3D0 net.inet.tcp.hostcache.expire=3D1 but this is not helpfull, the Load goes to 60% and the Performance is=20 also poor. How can i prevent this Problem? thanks for response r=E9 P.S. the same Computer with Linux runs perfect with Performance and 1-2% = Load, --------------ms080502010700070406080802--
