64bit Evolution Is Now Live

After that small hiccup with running Evolution on 32bit Linux and the memory limitations, we are now live on 64bit SLED 11 and the difference in speed is striking. The per user memory requirements have grown, but it's a small price to pay (and memory is cheap!). The top screen below is 220 concurrent Evolution sessions. CPU is barely used at all. Disks are configured RAID 1 which has proven to be the best for Evolution (RAID 5 is much slower). When using the Groupwise backend, hitting Send/Receive the dialog only appears for a split second. The server is has 4 CPUs, quad core and I think we could easily get 500 concurrent users on here with no performance penalty. I'll have a few days of tuning and minor issues. Next on deck for me: getting gdm fixed to allow XDMCP connections again, and starting to work on that new monster server to run Firefox.

Oh good. XDMCP in gdm. Nice!

@anonymous: I can't take credit for the physical coding to fix XDMCP, but will be working with the developers and testing with real thin clients. Hopefully that will be working in the next few weeks.

Why not try google chrome instead of firefox? It uses the same rendering engine as safari and is more secure.

@sejeff: I probably will be loading Chrome for testing with a small group of people. But there are a LOT of mission critical sites that we barely got them to make it work with Firefox. :) Banking sites are notoriously slow to make changes and we are happy they are out of the InternetExplorer only mindset. Chrome doesn't solve any "problems" for us. Firefox is working, fast, stable and all of the plugins are working. But of course I always watch new technology and monitor changes.
