We have a 2 server SharePoint 2010 installation, one FE one Index. Each is sitting on a different VM host. Each host has 256 gigs of ram with 4 8 core processors (32 cores). Each box is not over subscribed for either resource.
The 2 VMs have 16 gigs of ram each, and 4 virtual cores. SQL server is running clustered on separate VMs (also on separate hosts from each other and the SP VMs). The DB is on a very fast high capacity and high i-ops SAN with a 10 gig backbone. Performance from the SQL server peaks out at just under 800MBps (bytes not bits) and only comes close to that limit during the night when backups, consolidations and other tasks are being performed. The SAN sits at about 20% of peak i-ops.
The 2 SP boxes average 7 gigs of ram of usage, and 40% CPU utilization; but we are seeing page reloads in the order of 3 to 8 seconds, no matter what we are doing. Clicking on a list settings page, refreshing the front page; it doesn't matter.
Total content is around 2TB. Any thoughts on what might be happening? It's confounding us. Whats worse is this is not in production yet, with only a few users (IT) on it.
@Alex I did not see that one. Checking it out now.
@James I'll take a look and report back. The clients are running i5s with 4 gigs of ram and they are on our local network (100mb).
We are using Hyper-V rather than ESX
Here is the developer dashboard. I'm starting to lean on the Claims Authentication issue. The other 2 alerts only occur on this page, but the Claims issue occurs on every page, on every site.
Additionally, in the upper right and on our mysites our names do not resolve, they have \. In look up fields, if we click the resolve button, they do resolve.
