I have searched all over the nfs, enabled higher caching on nfs, enabled the usage of tcp, tried to pass hard, but transfer rates very poor, and only for nfs transfer, so it doesn't seem my network configurations are wrong as scp, html, ftp seem to work on full speed. On other machines on the network (non wireless) running same kernel (2.6.0) everything seems fine. Can anyone suggest what I could test to trace this problem?
