11.3 is stable for me as well, more so than any earlier 11.x release. It's even better than 10.0.5, which was rock solid.
You say you're using RH. Make sure you're installing the latest (RHEL 5.1). Do a clean install of the server, with no other software installed to ensure there's no confilcts there. Do a standard server install, then check in the wizard which dependencies are missing and install those.
Make sure your server has a fairly new-ish CPU (not neccesarily the latest on the market), and at least 1GB of RAM (more preferred).
Slow SWA usually points to the platform API set up incorrectly, or your IMAP cache corrupting. Of course, HDD speed will play a major role, but for a few users even a PATA HDD will be sufficient.
