Best performance with mounted Fat32 over NFS

5.02.2006

On my HTPC there is a 170 GB Fat32 partition which is shared with the local Windows XP installation. I want to mount that partition local and on other Gentoo PCs in my LAN via NFS. As I had issues with Konqueror displaying rapidly changing file transfer rates I tried different sync/async setting.

These turned out to be the best:

Tivo

/etc/fstab

/dev/hda5 /mnt/store vfat noatime,utf8,uid=65534,gid=100,dmask=0007,fmask=0117 0 0

Mount the partition as nobody:users, async is implied here.

/etc/exports

/mnt/store 192.168.0.0/255.255.255.0(rw,all_squash,anonuid=65534,anongid=100,async,insecure)

Export as nobody:users with async flag.

Caull

/etc/fstab

tivo:/mnt/store /mnt/nfs/tivo/store nfs timeo=14,intr,rsize=8192,wsize=8192,tcp,sync 0 0

Mount with sync flag enabled.

This results in stable transfer rates at about 5 MB/s (write) and 10 MB/s (read) via a 100MBit LAN.
