This question is only for people administering large KMS installations of 1000+ users.

1. What environment are you running KMS on? What's your hardware config?

2. What kind of performance are you seeing?

We're at 1200+ users on the hardware listed in my sig. We're seeing continual sluggishness on the server. Throughout the day, disk queue lengths are astronomical. And yes, we constantly play the "refcount/# of msgs in folders" hunt.

I'm curious about other large installation customers out there.

Seems that the "filesystem store" approach may be at its limits.

What are you using for storage? RAID array of some kind? With Kerio, the speed of the disk subsystem is the most critical part of the server.

PERC4e/Di RAID controller with a bunch of SCSI 10krpm disks in a RAID 5 config.
