Hello,

I have 4x45GB IBM ATA66 drives for FTP server to be filled up with ISO
images (~650MB). Access to this server is only from a hundreds of PCs
in 100Mb LAN. What would be you recommendation for FS/RAID 0
parameters optimized for downloading ISO images from FTP server at a
maximum speed.  The typical traffic is: cca 200 PCs downloads cca 50
different ISO images (FTP is mandatory) not exactly at the same time
(shifted about 100-200MB). FTP server uses sendfile(2) but could be
changed, of course.

I'm interested in parameters:
a) RAID 0 strip size
b) FS block size
c) FS fragment size
d) noatime
e) anything else?

Thank you.

Jarda
