Only 8 MB/sec write throughput with NetBSD 5.1 AMD64



Hi,

I am trying to set up an FTP/Samba file server for serving media files
at home and I am seeing only 8MB/sec disk write throughput with NBSD
5.1 AMD64. Previously Windows 7 and Linux did 30 MB+/sec on the same
setup. I just did a simple dd to check

dd if=/dev/zero of=/store/test.img bs=1000K count=1000

Setup details:

Asus M3N78-EM Mobo with NVIDIA GeForce 8300 chipset and Nvidia gigabit
ethernet (nfe driver in use)
AMD Athlon X2 2.6Ghz, 8GB DDR2
750GB WD 7400 rpm drive with 16MB hardware cache
Currently / is 40GB and I created a /store partition of 100GB size for testing
GENERIC kernel with no changes

How can I improve the disk write performance? What other data can I
collect to troubleshoot?

During installation i asked installer  to format /store with FFS2 and
softdeps on (although i don't know why fstab shows just ffs??)

# NetBSD /etc/fstab
# See /usr/share/examples/fstab/ for more examples.
/dev/wd0a               /       ffs     rw               1 1
/dev/wd0b               none    swap    sw,dp            0 0
/dev/wd0e               /store  ffs     rw,softdep               1 2
kernfs          /kern   kernfs  rw
ptyfs           /dev/pts        ptyfs   rw
procfs          /proc   procfs  rw
/dev/cd0a               /cdrom  cd9660  ro,noauto
