Installing Domain Controller drastically reduces write speeds
I've been having trouble setting trialling a new server configuration, where write speeds are dropping from 100Mb/s to 10Mb/s after running dcpromo.
I've got a Dell Optiplex 745 as a test system, with a Samsung 750Gb 7200rpm drive, with Windows Server 2008 R2 installed.
Write speeds before dcpromo:

After dcpromo:

Absolutely no idea what could be causing this problem. Any help would be appreciated

Hello,
if a server is promoted to DC write caching is disabled. More details:
