My 450MHz uniprocessor Sawtooth G4 handles fileserving just fine, to two
servers and several clients, plus automated backups. You need RAM and fast
I/O more than you need CPU in that configuration (mine is FW800 to a RAID 5
array, with a full load of RAM).

I ordered the 450mhz replacement. Are there any things I can do it improve my server's performance?

Not an expert on this, but maybe adding an SATA PCI card and SATA
drives.

The throughput is limited by the speed of the bus. PCI bus speed is normally
33 MHz, at 32 bits this results in a peek throughput performance of 133 MB/s.
http://en.wikipedia.org/wiki/Conventional_PCI#Conventional_h ardware_specifications

If the cards would be running with 66 MHz it will double the throughput.

Using a Ultra ATA/133 PCI card will technically and logically use up 100% peek
performance of the PCI bus. If other PCI cards are installed alongside, the
performance will drop.

Don’t know how much a SCSI card will give you.

Don’t know if a SATA card is cheap to get, but SATA-1 will suffice.

Kind of depends on what it's doing. You said it's an FTP server, so it's mainly IO. That's disk speed and network speed.

What performance issues are you having? Remember if you're serving through a local network you'll get n=better performance than if you're serving to the WAN, unless you've got a really great internet connection. Most home systems are ~10-12 MBPS and they start crapping out waaaaay before the limit.

Here are some general hints:

A friend suggested I upgrade to a G5 tower, after my G4 QS 2002's cpu
went bad ...

I'm doing mostly involved photography processing in the HDR area
now ... so speed is a good thing.

All my applications are 32bit style coding ... will I run into any
problems with G5s in general?

What about the cooling systems ... didn't some of them have problems
with the liquid cooling idea?

I have a number of PCI cards that are still good ... what ideas do you
have here? I may just wait for a QS Dual 1GHz cpu to appear, and
consider going with an MDD for increase in speed in the future.

Suggestions on which ones in the G5 family (and others) to consider
are welcomed. Not too fat in the wallet ...

I'm currently using a G5 DP 2.7 GHz, I got it used 1,5 years ago.
Great machine: fast, very silent (liquid cooled), easy to access its
innards, very stable (I'm using it with OSX Tiger).
Its only drawback, so far, it's power hungry: it draws from 160 Watts (idle)
to over 300 Watts!

It's way faster than the G4 Digital Audio (originally 667 MHz, upgraded with
a 1.4 GHz CPU) that I had before. A big step forward.
If your QS felt slow, I suggest going for a G5 (2.0 GHz or above): you won't
need to change your software (no OS9 boot, though!), but it will be
snappier.
Depending on where you are, I think G5s start from 100-150$ and up.
Definitely worth a check.

Regarding realiability, I read G5s with Delphi liquid cooling are
troublesome, but mine has a Delphi one, and so far - knock on wood! - it
runs flawlessly.
I think it's a matter of luck. If you don't feel like gambling ;-) better go
with an air-cooled one (the 2.3 GHz DP seems the best choice).

Here you can find info and specs about all the G5 models:

I have been using a G5 Quad Core with later cooling system fix for a year and no problems. I am using Protools with SSD and FireWire drives. I think it's an amazing inexpensive tool.

Cheers,

I went on and bought a G5 Quad Core 2.5GHz

By later cooling system fix, do you mean the last cooling system that
fixed the earlier leaking problems?

Is there any preventive maintenance you would recommend?

not hardly specific to teh G5 quads, but I think all these suffer
from the dread Capacitor Plague form the period they were
manufactured...
while it's a singular cause (really bad quality power suppky
capacitoers from a specific vendorfor severakl years) the SYMPTOMS,
as some/all/none of the caps start to get flakey can look like
ANYTHING else going confusingly, randomly wrong with the system.
