I'm trying to develop a MicroFiler solution during my training period. I
would like to know if the performances are ok.
I'm using two fujitsu Bi Xeon 1800, 512Mo, 2 raid 1 scsi disks. They're
linked on a 100Mb network.

This is my bench results:
              -------Sequential Output-------- ---Sequential Input---
--Random--
              -Per Char- --Block--- -Rewrite-- -Per Char-  --Block---
--Seeks---
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU  K/sec   %CPU
K/sec  %CPU
           10  5778 27.1  7763  3.8  7674  4.5 20455 99.9  1159289 113.2
3164.9 15.8
           50  5815 32.1  7826 10.1  7672 11.5 20822 100.0 1169697 114.2
1479.7  9.2
          100  5490 33.6  7125 14.3  7030 14.6 20331 99.7  1117294  98.2
3169.1 15.8

Here, we're using a Net Appliance Filer Solution based on NFS.
This is the results of this filer
              -------Sequential Output--------     ---Sequential Input--
--Random--
              -Per Char-  --Block---   -Rewrite--  -Per Char-  --Block---
--Seeks---
Machine    MB K/sec %CPU  K/sec  %CPU  K/sec %CPU  K/sec %CPU  K/sec   %CPU
K/sec %CPU
           10 28147 101.7 482518 141.4 454545 88.8 27625 99.8  1279840 125.0
98176.4 294.5
          100 28503 99.9  473138 101.7 474682 97.3 29106 100.1 1292766 101.0
94607.4 307.5


I don't want to get the same results as the NetAp Solution, but i want to
know if i get the best result that Open AFS could give me.
