Well, I part-own a Mac/Linux support company in New Zealand with
several Linux boxes in Prepress and design (in fact, we offer a NT to
Linux Upgrade!)
Our latest system is a Intel Lancewood motherboard with a PIII-550
connected to 70GB Ultra2 RAID.
When you do a /sbin/hdparm -tT /dev/md0 on the machine, you get:
Timed cache buffers reads of 144MB/sec
Timed disk reads of 60.32MB/sec
That's a fast motherboard and a fast RAID...
Now, over 100BaseT from a Power Macintosh G4/450 using Appleshare
over IP, we get 9.8MB/sec with Helios Lantest 2.5.2. Yes, that's
MegaBytes...
Copying a 500MB scan to the server finishes in less than a minute.
Our customers are impressed!
I use a modified version of asun214 37b, and it runs VERY well.
Just my input.....
