Re: Optimising NFS for system files

. But : - tar is directed to /dev/null so that should avoid any physical writing ; - there is still memory FREE on both server and client while taring ; - the effect of tar is the same on server and client, so the induced error should be the same time on both. Thanks a lot, Best regards, -- Bernard DUGAS

Re: Optimising NFS for system files

a sidenote, you are probably getting a version of time integrated to your shell. The -h option works fine in /usr/bin/time, so run like this: client6# /usr/bin/time -h tar -cf - /usr /dev/null Very true, this is it :-) Thanks a lot for your help ! Best regards, -- Bernard DUGAS Mobile +33 615

This is a Gbps network with only 1 switch between nfs server and client, with less than 0.2ms ping. So bandwidth should not be a problem, seems that NFSV3 is the limitation... Trying to change mtu, but don't look easy, where can i find the possible range for ports ? Best regards, -- Bernard

Optimising NFS for system files

Hi, I'm working on a project to have many diskless clients PXEbooting on 1 nfs server. With some help :-) i could manage to share almost all system files (/, /usr,..) through NFS. i can see a reading speed difference 4 time slower on client than on server (time tar -cf - /usr /dev/null).
