We're currently running KMS 6.08 on a Windows 2003 server...and it's as slow as a bloody dog. At times it's unbearable watching that hourglass spin for minutes before our folders begin to draw in

Does anyone know if it makes a difference in speed to run KMS from an Apple server? I'm just about ready to try anything at this point.

I suppose it depends on the amount of users / network specs etc. We are only around 35 users running 6.08 on a Dual 2.3 G5 and it flies - even with the web interface.

I would imagine the bottleneck will be network speeds rather than server performance though as the cpu's in our server barely reach 5% most of the time. I'm running two 24 port 1Gb Netgear switches linked via fibre, our users are 75% pc's and 25% macs.

Most of the outlook users haven't noticed any speed change from our previous Exchange 2000 server (ran on a win 2000 server) but the IMAP users have noticed a massive speed increase with the new apple server. Our old server used to do everything though, from file sharing through to email, whereas now we use an xserve for email alone.

I have heard Webmail is crap so much it isn't funny.. what about webmail brings upon this hatred. I have over 8k in messages and 1.2gigs of email.. Webmail works faster for me than a client... Granted, I can't do return recpiets which is a nice thing for me.. but overall I don't think Webmail is bad at all. It could be worse.. you could be using MAIL at a command prompt instead.. try sifting through 8k of messages with that...

As for Server Platform, we have about 100 users running on a 2.4ghz P4, 1gig of RAM and 400gigs of RAID'd disk space. The only time I notice a tick anywhere in the system was the Archiving glitch that shows up in some ditro's of Linux. Nothing too bad IMO.. just annoying.. I just do backup manually or more accurately through a CRON job instead. I imagine a Xserve would run this stuff like a top.. but seeing as a shoestring budget is about 12 strands of string more than mine... Off the shelf Hardware it is..

We used to run KMS on a G5 1.6 with 2GB of RAM, with 160GB RAID, but for 20 users this was overkill!

We now use a headless Macmini 1.42 with 1 GB of RAM. Works like a charm. I rarely see cpu over 10% and memory never gets anywhere near its limit even during archiving. We archive to an external FW drive.

Webmail works just fine. We have no windoze users, so I can't comment on Outlook issues and we don't use any of the calendar options either! For us, KMS works very well.

We run KMS on a headless 400MHz PowerMac G4 with 1GB of RAM and a 250GB ATA100 drive.

It has run flawlessly for the past 6 months adn even on an old G4 i rarely see the CPU hit go over 50%.

Disk throughput and network speed appear to be the biggest factors in getting the best result from KMS.
