Hi,
what kind of discs are you using for your KMS IMAP Mailserver?
Is it SCSI or IDE, is it RAID or just one disc?
Have you ever measured the speed and are you satisfied with the over all disc performance?
I ask this questions because I may have to size a new KMS Server and would like to know your experiences on disc speed.
I use iometer form http://www.iometer.org/, which is available for linux and windows for the speed tests.
As a testsize I used 32k patterns and came to the notsofast speed of 2.5 mbytes/sec, while 170 Users were connected to the imap KMServer.
I have a proliant 320 with 1.1 GB RAM and a IDE Mirror configuration running w2k server and no other services on that machine.
Not one of our users is complaining about speed problems, but as we are hosting around 30 GB of maildata (and growing), I am a bit concerned about the speed of the IDE drives...
I would appreciate if you would report your disc speed and disc configuration.

regards

Oliver

I too am interested in any opinions as I'll soon have a similar situation.

OS X, PowerMac G4, DP 1.25GHZ, 100 Users

ATA 7200 RPM or UWSCSI 10K RPM??

UWSCSI worth the extra cost compared to performance gain?
