comment NFSv3 client differences in read/write performance
@matt: Can't say much about the server, clients are RHEL 5.8/6.3 running Linux 2.6.18-308.11.1.el5 and Linux 2.6.32-504.8.1.el6.x86_64 .

comment NFSv3 client differences in read/write performance
@matt - the clients are physical, the server is physical at the core, but presents itself to the client as virtual (vFiler - essentially it's a really beefy corporate NFS filer).

comment NFSv3 client differences in read/write performance
@tigran - I am aware of network latency and server processing time - see me mentioning RTT. What I wonder is: considering BOTH r/w report 50-100ms RTT (which includes server processing time) why do reads take 200ms to execute fully, but writes 200sec? Where does this x1000 factor come from?

Is there any command with which I can count the unix domain sockets (like netstat -t | wc -l for the tcp sockets)?
