Hi,

:The default rsize/wsize on Linux is 1k, due to those silly cheap Ethernet
:Boards, which are so widespread in the PC market (like those dumb NE1000).
:Those boards are not able to receive 8k Back-to-Bakc packets without loosing
:some of the packets. The NFS performance would go down to zero in this case.
:If you use better boards (with at least 16 k Buffer, or DMA access, or PCI
:boards), then you could add rsize=8192,wsize=8192 to the mount parameters, and
:you will get high performance.
Now, from the nag I get an idea how to do this from the command line ...
but how is this done as entries in /etc/fstab? The same? just stick
the rzise ans wsize at the end with the other options?
TIA,
