That is good to know. We are on Windows 2008 R2 currently, but planning on deploying to 2012 very soon.
The Remove Analytic task was enabled and running monthly. It didn't show failed, but does have the external task check box, checked. Maybe we didn't get report back because of that.
This one kentico instance seem to still be using more RAM. 1.5 to 2.0 GB at times so there is likely something else missed. The code is identical to other instances on the same server, but this one is slower and using more ram, but speed is back to normal now that the 2 million file directory is gone.
