FreeBSD and newer HDD problems ?
Hello, I've recently bought new big HDD (WDC RE, 320GB) and it looks like FreeBSD has some troubles with it when trying to transfer files over network. If I try to perform some synthetic test like 'dd if=/dev/zero of=/wdc320/testfile' then I get some decent speeds about 40MB/s. When I try to copy some big files from my older disk (IBM 40GB) I still have write about 25-27MB/s. Problem comes when I try to copy something to disk over network (tried samba, ftp) disk write speed is very low - about 5-6MB/s at max. When testing this issue I've start 'systat -vmstat 1' and noticed that my new disk is very busy (60-100%) and speed (MB/s) jumps up and down. If I write files with 'dd' or transfer them from disk 2 disk then write speed and disk load is almost constant (about 60%). When transfering files over network to old HDD then disk load is low (40-50%) and speed is constant (8-9MB/s). To be sure that disk it is not some kind of disk problem I've installed Debian 3.1r2 with same version of samba and I get 9-11MB/s transfer speeds (in both directions) !! Also it doesn't matter if I use transfer data over gigabit card or 100mbit card. Results are similar. FreeBSD is in avarage very very slow (3MB) while Debian works fine (10MB). Because my server is primarily used for transfer files (Samba + PDC) it is crucial for me to have highest transfer speeds possible and I'd like to stick with FreeBSD :-/. Does someone has any idea what could be wrong or how could I determine what causes this problem ? Thanks for any advice.

The speed through 100Mb/s Ethernet will be around 5 or 6MB/s and probably you can't go any faster due to your hardware limitations (switch, cables, processor, controllers and especially their drivers). Currently there are a few active threads related to similar issues (controllers and their drivers).

Hmmm so how you explain that with Debian system on SAME machine I'm ABLE to get transfer speeds about 10MB/s ?? Or do you mean I can't go faster with FreeBSD and only solution is switch to Linux ?? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I'd blame drivers. The other question I won't answer, but you might find explanation by following the threads I gave you. Apparently, there are some issues with some controllers and their drivers.

What SATA controller are you using?, and have you tried this with FreeBSD 6.1? if not you should. It is PATA controller on i845 mobo so it is quite old. It works in UDMA100 mode. Next week I will probably try to hook it to ATA UDMA133 PCI card to see if there is some difference. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
