I don't know if it helps with the suse distribution, but I has a similar
problem with DLD (Delix).
NFS transfer rates have been only approx. 300kBytes/sec while ftp between the
same machines works at 1MByte/s (10MBit Network, full-duplex, twisted pair).
The only thin I had to do is changing mounting options for the nfs filesystem
on the client in etc/fstab:
HOSTNAME:/share /mnt nfs noauto,user,timeo=2,soft,intr,rsize=8192,wsize=8192
The increased rsize and wsize (Kernel defaults 1024) brought up speed to
Warning: this options seems to work only on kernels starting 2.0.34 or all
2.2.x. On older Kernels, mounting of the share will fail using this options!
Another problem may be network card settings or cabling. If you have mixed
full-duplex and half-duplex on one cable, you'll get collisions. Take a look
at /proc/net/dev, there you'll statistics.
Hope this helps,
