u could try the following for tuning nfs
RPCNFSCOUNT=64 in /etc/sysconfig/nfs
Add the following lines to /etc/sysctl.conf: net.core.rmem_default = 262144 net.core.rmem_max = 262144
Increase the fragmented packet queue length upper and lower bounds
net.ipv4.ipfrag_high_thresh = 524288 net.ipv4.ipfrag_low_thresh = 393216

Hi, I have 2 computers connected with Ethernet LAN(cross cabled) and both running Fedora Core 1. I m running nfs server on one of them. My problem is that whenever i copy a big file (about >10MB) the speed of copying reduces drastically and sometimes it even stalls . However when i copy the file using http/ftp then there is no problem. I have tried using following options while mounting in nfs rsize=8192,wsize=8192,no_wdelay etc.... I have also tried using tcp option but it did not help.
Please help, CHIRAG.
