FreeBSD-amd64, nforce3 and very slow disk transfer
Hi all,

I've just bought an ASUS K8N-E mobo. I'm using FreeBSD-5.3-Stable (amd64) and suffering from *very* slow disk transfer rates. The chipset is an nforce3 and is correctly detected at boot :

# dmesg
atapci0: <nVidia nForce3 Pro UDMA133 controller> port 0xffa0-0xffaf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 8.0 on pci 0

My disk is an UDMA100 one, everything seems to be correct :
# atacontrol mode 0
Master = UDMA100

# sysctl -a
hw.ata.atapi_dma: 1
hw.ata.ata_dma: 1

The whole system is very very slow. Copying a 600 MB takes about 10 minutes (1 MB/sec) and makes the system nearly unusable during the copy.

Do you have any idea ?


Note : it could be very great if nvidia could release nforce drivers for FreeBSD, not only the linux ones........
