Not to complain, but rather as constructive criticism, I think the current state of NFS in the kernel or otherwise is completely horrible. Granted, I am no NFS expert by far, however I can't get any decent performance out of the thing at all.
I've got a 3 machine LAN here, 2 RedHat 6.0 boxes, and 1 Win95 box. I've got some dirs exported via nfs, as well as via samba.
If I transfer a 100M file from one Linux box to the other via NFS mount, I get around 250k-290k per second. If I copy the exact same file via Samba instead, on the same two machines exactly, I get 800k/s or higher. If I transfer in the other direction, the results are the same as well. If I copy the files from the linux box to the win95 box via samba, I also get around 800k/s.
One might be quick to say "your samba transfer was cached in memory from the nfs transfer", however I have transferred files with SMB first too, and then NFS, and there is NO difference, so caching does NOT play any part. Even if it did, why would SMB file transfers that were not cached to start with go through at 800k/s?
Anyways... I am using NFS between the Linux boxes as it is more transparent and preserves permissions, etc... I can then administer the shares and whatnot from nfs, which are then visible to W95 boxes on the LAN read-only. This was my goal anyways, but with NFS topping in at 1/4 the speed of SMB, I must say that I am very disappointed.
That said, it COULD be that I am a ningcompoop with things not configured right... Any NFS tuning hints/suggestions?
I am using a homebrewed official 2.2.11 kernel on RH6.0 with NO patches applied. Do I need to upgrade any NFS packages as well?
Any help would be greatly appreciated. Thanks. TTYL
