FreeBSD 7.0-RELEASE getting terrible throughput using sk0 adapter
I recently leased a godaddy.com dedicated server, and while they didn't offer freebsd as an option, I used the fine guide at http://www.freebsd.org/doc/en/articles/remote-install/ to get freebsd installed. I noticed that the installation was taking a long time with ftp as the source media, but I had thought that maybe I just picked a bad mirror. After the install was complete, and I started to install some ports, I was still seeing really slow download speeds. I then decided to see if something was wrong with the system by downloading the same image from the same source that I downloaded on linux in order to bootstrap freebsd and the speed difference was appaling. It had downloaded at 10.29 MB/s. Once freebsd was installed, It will only go at 60KB/s.. I have tried messing with the options mentioned here: http://spatula.net/blog/2007/04/freebsd-network-performance-tuning.html but that provided no results. Here is some info about my setup: dmesg and the output from sysctl net.inet are attached as files fsserver# netstat -I sk0 NameMtu Network Address Ipkts IerrsOpkts Oerrs Coll sk01500 Link#3 00:30:1b:44:4d:4d16318 013163 0 0 sk01500 72.167.50.0 ip-72-167-50-116.15896 -13161 - - fsserver# vmstat -i interrupt total rate irq18: fwohci0+2 0 irq19: skc0 uhci1+ 51928 46 cpu0: timer 2138741 1921 cpu1: timer 2128730 1912 Total4319401 3880 %netstat -I sk0 NameMtu Network Address Ipkts IerrsOpkts Oerrs Coll sk01500 Link#3 00:30:1b:44:4d:4d32321 025510 0 0 sk01500 72.167.50.0 ip-72-167-50-116.30854 -25508 - - any help is greatly appreciated, let me know if there is any more info that I have forgotten to include that might be needed. dmesg.boot Description: Binary data sysctl_net.inet_output Description: Binary data ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

still seeing really slow download speeds.

It had downloaded at 10.29 MB/s. Once freebsd was installed, It will only go at 60KB/s.. looks like problems with speed/duplex autoconfiguration with the switch, or bad support for PHY in FreeBSD. what you describe is quite common case when one side gets configured for full duplex, other for half duplex. as it works for linux, maybe PHY support in FreeBSD is buggy. try setting up speed and duplex options manually ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You may need to have a tech there do it for you. Your box has the sk NIC and usb sharing an irq. The NIC driver is MPSAFE but the usb stack is still under the GIANT lock. Disable usb and the NIC driver should perform better. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

From server support live chat: Steven H. - Server Support: Submit a trouble ticket and we will look into it further. I'm pretty sure they will not disable usb since the DC technicians need to boot from USB in some cases. So is there any other way to verify that this is indeed the problem? Perhaps as Perry suggested, building a kernel without usb/firewire, or possibly setting the irq manually so it's not shared? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
