While I have researched many, many complaints of SBS 2011 performance issues, most relate to network performance.
My problem, on the other hand, is that working AT THE SERVER CONSOLE is super slow. Doing practically anything at the server is slow. Apps launch slowly. Event viewer takes forever to list the events, EMC can take a couple of minutes before the contents of the EMC are available. When launching apps that use MMC, for instance, I will get the "adding snap-in to console" dialog box. Quitting it I will get "waiting for snapin...".
I have many clients with SBS boxes and this one is by far the slowest. It's no slouch, either. A Dell R620 with 32GB RAM, Dual 2.9GHZ XEONS, each with 8 CORES, hyperthreaded giving 32 total "cores". I've got 8 x 300GB 10k drives in RAID 50 on a Dell Perc 710P Mini w/1GB cache.
At first, it seems like the CPU clock speed is fixed at the lowest possible non-turbo, low power speed. But I have no way to confirm. CPU usage is generally low. I have CrashPlan Pro and Dropbox installed on the server. I think those are the only 3rd party apps. It's just as slow on a Sunday morning (when zero users are on it) as midday on a work day.
It's just outright sluggish. Nothing at the server console happens quickly. Even getting OWA or RWW to come up can take 20-30 seconds or more.
I've run the latest BPA and it literally only found one item, and it was not related to anything that would affect performance.
Could so many "cores" be causing a problem? I'm open to any ideas. Thanks!
