Hi,

Currently, I use version 6.1.4 and I have to upgrade to 6.3.0. Does anyone have experience about A.) webmail speed B.) Load changes on the server? At this point, I have 1020 mailboxes on the server and simultaneous users vary 200-300 in webmail, 30-40 in KOC and about 50 IMAP or POP. Messages comes in about 500/h, SMTP sessions 1500/h

Server loading is very IO intensive. "IO Wait (wa)" value keeps over 50% and in worst case, it goes over 90%. CPU load vary 30%-60%. Memory usage (mailserver daemon) is usually 800Mb-1,5Gb, depends KMS memory leaks ;)

The platform is RH ES4, 2 x Xeon2.8HT enabled, 2,5Gb DDR266, Hardware RAID1. So there are no too much resources left and I don’t want any performance disasters after upgrade. I would like to hear your experience about performance.

I do feel KMS has made strides in speed the last couple of versions, so in that respect the current KMS is faster/more efficient than older KMS versions (as yours).

However, this is moslty about end-user experience: webmail runs faster, KOC runs smoother. Whether or not this is also true for the server side, I don't really know. I would say so, but it's a tricky question.

I would possibly advice you to invest in a faster disk subsystem if you feel your server can 'just barely' handle the load. Perhaps upgrade to RAID-10, as this will almost double your read&write performace (not the latency part, helas). Don't use RAID-5, this will speed-up reading, but possibly slow down writing.
