We recently installed a Windows Server 2008 R2 (64) [Dell R720, RAID 10, 32 GB]. Initially the performance was fine with one SQL Server 2008 R2 (64) and a Tomcat 6 (64) installation.
Then the server started to become slower. At first we assumed something to be wrong with the NIC drivers (Broadcom BACS), so we upgraded their firmware, and the drivers, which seemed to have helped.
But now, after some time (about two months) we're back in the same place. Starting Firefox takes about one minute, EVERYTHING is awfully slow.
Checked so far:
1) perfmon shows peaks but nothing special
2) procmon (following FF's start) shows no indication
3) Latest patches/hotfixes installed
Is there anyone out there experiencing similar problems on the above-described hardware?
