Hey all,

We're having some very slow speeds on our local network. Users are complaining that bringing up a message is sometimes taking anywhere from 15 seconds to a minute or more at times. Refreshing, opening a folder, everything is very slow. Even changing folders has a significant delay associated with it.

Part of these slowdowns seem to be related to IE. All of our users are running WinXP, using a fully updated IE as their browser. Using that, they see the very slow webmail access. Using a browser like Firefox though seems to really speed things up. There are still some slowdown issues, but it's typically much faster to refresh, change folders, etc when compared to IE.

The server is a Linux server, running Fedora 3. It's a P4, 512MB of RAM, 80GB IDE hard drive. Nothing huge, but we have a total of 30 accounts set up, and typically only have around 20-25 concurrent connections. System utilization is very low overall, with only slight spikes in CPU usage, low memory usage, and low network usage. In short, it does not seem to be a system bottleneck we're hitting here.

Our version of KMS is 6.1.0 patch 6. Things were slow prior to the patch as well.

I'm curious to know what I might be able to try to speed things up.. or where to even start looking. Any suggestions on what to try to possibly speed things up?

Submit a ticket with us ( We will want to have an email account on your system, so we can test from here, and see if we can reproduce the slowness.

This will tell us if it's an issue local to your system/network, or perhaps a bug.

Check the local computers CPU load when handling Webmail. I've found Webmail in IE to be quite CPU hungry, so it is not very responsive on older machines (say slower than 1-1.5Ghz).
