Hi,
we are getting calls from the network team blaming us for high latency caused by SCCM updates. We run in native mode and use port 8531 for coms with WSUS.
The volume of data per client this month seems to be roughly the same, around the 60Mb mark per client connection to the WSUS server - which is also the primary.
I cherry-picked a few machines from the reported clients generating high traffic and checked where the clients where getting content from and all are getting as expected, from their local DP. so I dont understand the volume of 60Mb+ on the communication between the client and the WSUS running on the primary? surely the update scans against the WSUS server would only generate a small amount of traffic (not 60Mb) and once it works out what it needs it then looks for content locally? I assumed that these client were, for some reason, downloading from the primary DP which would explain the volume of data, so I was surprised that these client are actually getting content, as expected, from the local site....
can anyone explain the possible reason for high data volumes specifically to do with updates, as the traffic is all over port 8531, between the client and the WSUS server when it is receiving the actual content locally and not from the primary DP?
thanks
