Can someone explain to me this  blazing speed?

dd if=/nfs_mounted_rep/testnfs.bin of=/dev/null bs=16k
16384+0 records in
16384+0 records out
268435456 bytes (268 MB) copied, 0.0883431 s, 3.0 GB/s

My options in fstab are:

 nfs defaults,noac,_netdev        0 0

Both servers are on the same LAN.

That is a very small file size to test with, try increasing it relatively significantly and see what throughput rate looks like.  Since this transfer took less than a second you are seeing an inflated transfer speed.

Thanks.  I have used a 5GB file and the speed was more regular. :) 37mb/sec
