nfs sucks!

Hello there!

My little server was able to handle nfs operations at 9MB/s until since a few days there were only 2.5MB/s second usual. Today I tried to ask google, and found an interesting entry that the kernel-developers did a f.*** mistake and set some buffer from 4M to 32k but that using nfs3 and nfs over tcp would help. So I tried and now I'm stuck at 63K/s this isn't very funny I say. My clients come along with big knifes and trying to kill me. So please help me :O)

My nfs works at the full 100Mbit.

I just:

enabled all the nfs options in the kernel
did rc-update for netmount and portmap on the client
updated fstab on the client
emerged the required nfsd package on the server
did rc-update for nfs and portmap on the server
edited hosts.allow and exports on the server

Bingo it works.

I have 3 shares totaling 100Gb, they mount instantly. Vanilla kernel 2.4.19

Do you have good network cards and are you sure that the linux drivers for your card are solid?

I use netgear fa311 10/100 cards, very cheap but use the natsemi driver which is totally solid. 380 days uptime with no faults, only reason it got turned off was because I moved house.

Don't know whether this is relevant, but I got quite a performance increase form adding:

nfs also (has always had) major security problems

Thats why we have nfs4, which takes care of most (if not all) security issues.

Please make sure that you are still running portmap. Makes one hella difference I've noticed :-)

I know this thread is ancient (as far as these forums go), but I was wondering if Sven is actually using NFS4? I was under the impression that the userland stuff for NFS4 isn't there yet. Is that wrong? Also, do you need kerberos for NFS4?
