Hello list, I am facing with really slow network performance (nfs/ftp) under FreeBSD 6.2-PRERELEASE with em0 NIC connected to Cisco Catalyst 2950 switch. The transfer speed is ~150-200kbps for nfs, ftp and httpd. Here is more information about my setup:
em0: <Intel(R) PRO/1000 Network Connection Version - 6.1.4> port 0xdc00-0xdc3f mem 0xfcfa0000-0xfcfbffff irq 54 at device 4.0 on pci3 %ifconfig em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=b<RXCSUM,TXCSUM,VLAN_MTU> inet 192.168.1.5 netmask 0xfffffff0 broadcast 192.168.1.15 ether 00:04:23:c7:61:3a media: Ethernet autoselect (100baseTX <full-duplex>) status: active The server is connected to Cisco Catalyst 2950 switch (latest IOS) with 'auto' set for duplex and speed. 'sh int' shows 100baseTX and full-duplex. I googled two threads with the similar symptoms: http://www.daemonnews.org/mailinglists/FreeBSD/freebsd-performance/msg01732.html http://unix.derkeiler.com/Mailing-Lists/FreeBSD/performance/2003-06/0014.html Tried everything mentioned there, but it didn't help. I tried to set 100baseTX and full-duplex both on FreeBSD and Cisco - same slow throughput. Also tried to play with sysctl - no luck. netstat -i doesn't show anything suspicious: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll em0 1500 <Link#1> 00:04:23:c7:61:3a 21401 0 31364 0 0 Anyone with the similar problem? I am ready to provide more detailed information and I would highly appreciate your assistance! Thank you in advance. _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
