Hi, all.  Came upon something I've not seen before.

Trying to push the Config Manager client to a new server, it was going excruciatingly slow.  Reading up on it led me to look at BITS stuff.  Settings were all good - non-existant, actually.  The only thing that helped was to change the job's priority from Normal to Foreground.  That got the transfer done more or less instantly.

So now the client's installed, but there are new BITS jobs stacking up.  I can't get any Windows Update info from it to the CM server, etc.

Now, this server sees a sustained 250-275mbit/s of inbound network traffic pretty much all the time, just by nature of the type of server it is.  That leaves several hundred mbit of slack, though, as it's got a 1gbit connection.  But BITS seems to be acting like its starved for bandwidth, and transfers are slow, even when the CM client is setting priority to high.

We've got a server that fills an identical role and is running on identical hardware with the same NIC driver on the same network that sees even higher sustained inbound traffic (currently ~1.2gbit/s on a 3gbit/s team), but without any of this type of problem.

Anyone know of a way to force BITS to be a bit more aggressive, so that things actually work?  Or maybe I'm going about this wrong?


E.g. ~22.5 hours after it was created, this WU job finally started, and 20-30 min after that, is only 7MB along.
