WSUS downstream servers sync updates slowly from WSUS Upstream server RRS feed

  • Question

  • Hi,

    We have a WSUS environment with one server as WSUS upstream server which downloads updates from Microsoft and remaining WSUS servers spread across the locations as downstream servers. The downstream servers sync with upstream server and download updates from upstream server. The sync is succeeding but the download takes forever to download all the updates from upstream server. Is there a way I can speed up the download at the downstream servers?

    Thanks & Regards

  • Hi Sitaram,

    Thanks for your information and could you please kindly advise below details?

    1. Please kindly identify the downstream server is a replica or an autonomous server.
    2. Please kindly advise the update files size that you fail to download.

    BTW, I try doing some research and find a similar thread as below for your reference

    Hope above information helps.

    Best Regards

  • Hi Tina,

    Thanks for the reply.

    1. Please kindly identify the downstream server is a replica or an autonomous server. - The downstream servers are replica of the upstream server.
    2. Please kindly advise the update files size that you fail to download. - When I check the Download status, I see Updates needing files: some thousands ex: 3,878 and Downloaded x MB of y MB ex : 108,242.44 MB of 195,405.75 MB .

    The above numbers vary for different downstream servers.

    Upstream and downstream server version : 6.3.9600.18838

    Port being used is 8530

  • What you're looking for is to force BITS to download using Foreground mode.

    Open PowerShell as an Admin on the WSUS Server and run

    $conf=(get-wsusserver).GetConfiguration()
    $conf.BitsDownloadPriorityForeground=$true
    $conf.save()

    Your downloads will be fast again as they will download in the foreground rather than in the background.
