I'm wondering if I need to tweak something in my scalix server to get SWA to run faster. Just to let you know the speed of SWA...
1. To initially load SWA in the morning when I come in to work takes about 2-3 minutes
2. To load any folder such as drafts, sent items etc takes about 30 seconds even if the folder only has a single object
3. We only have 3 Outlook users and 3 SWA users!
All in all I really like scalix.. We've been using the server for over a year and it's very solid.. I hardly ever have to touch it. Once in a blue moon I'll need to go in and 'service scalix restart'. up until this last reboot I had over 6 month uptime.
Here are some stats:

I bumped up the tomcat memory allocation based on what I read in some forums and rebooted.. still didn't seem to help much
