Is it just me? Can anyone confirm success using Olaf Kirch's latest nfs
package (kernel-based server & async write support) under later kernels?

It appears to work fine for small transactions, but all transfers
involving > 1-Meg (or thereabouts) result in a dead server - and
occasionally a dead box.

Hi,

i am running 2.1.42 and it is fine as long
as the client mounts with rsize / wsize of 4096.
I did run bonnie -s 256 on an nfs drive and the
performance was really fine. (You'd laugh at the numbers,
but my experimental box is a 386, client was P133/128MB 2.0.30 :-))

I see similar problems with wsize=8192 as you.

However ping -f -s 8192 -c 5000 will give a maximum reply of 250
packets, so i belive that the IP packet fragmentation code has a problem

Ciao
