My WSUS 3.0 server constantly got transfer rates between 10 and 30 kB/s. I searched for a solution to control the download speed, but I couldn’t find any way to configure the WSUS download behaviour.

Finally I found out that I only needed to set BITS in foreground mode. In WSUS 2.0 this could be realized by downloading the WSUS debug Utility and the command “wsusdebugtool.exe /tool:setforegrounddownload“. Unfortunately the debug tool doesn’t work with WSUS 3.0.

But luckily I found another problem solution at KB922330

If you are using WSUS 3.0 with a Windows Internal Database that was created by a default WSUS installation, type the following command:

%programfiles%Update ServicesSetupExecuteSQL.exe -S %Computername%MICROSOFT##SSEE -d "SUSDB" -Q "update tbConfigurationC set BitsDownloadPriorityForeground=1"

If you configured WSUS 3.0 to use an existing installation of SQL Server, type the following command:

%programfiles%Update ServicesSetupExecuteSQL.exe" -S %Computername% -d "SUSDB" -Q "update tbConfigurationC set BitsDownloadPriorityForeground=1"

Now restart the Update Services service and your WSUS 3.0 will leech at full speed.
