Hi list,
We've had an interesting NFS performance issue with the following setup. Clients : CentOS 5.5, kernel 2.6.18-194.el5 Server : Solaris 10 kernel Generic_142901-08
Reading a file (not cached) with dd : dd if=file1 of=/dev/null bs=1024k count=100 performance is around.. 700 kB/s !
/proc/mounts shows rsize has been negotiated to 1mB
Have you tested the same thing with a Linux NFS server?
The CentOS 5.x kernel has a maximum server [rw]size of 32Kb, so you would need to use something with a more recent kernel to get [rw]sizes to be 1Mb.
