EV, Vault Cache, Saturated Link

[MASIV]

I have searched around but cannot find any definitive answer to this question:

We have been running EV for about 3 years now.  Recently upgraded to EV8.0.4.  I have enabled the vault cache/virtual vault cache.  When users enable the vault cache, it begins the caching and seems to dominate the link to the site.  These sites are connected via T3. 

Doesn't EV throttle down when it is exchanging information so it will not saturate the network link?

EV controls the ate by using Background Intelligent Transfer Services (same mechanism used for WSUS and regular windows updates) and i think also requires QoS to be enabled on the adapters check this out, might help you further http://msdn.microsoft.com/en-us/library/aa363133(VS.85).aspx

Personally, I believe this to be a problem with the router setup at the affected locations (there are 2).  We have 80 remote sites and these are the only two that are affected by traffic problems.

Thanks for the info.  I will check it out.

BITS will "normally" use all available bandwidth.

I've seen this from a different angle by a different customer.  With that customer even on good links BITS was taking *weeks* to download anything.  Turns out they had a GPO in place which limited BITS to 10 Kbit per client machine.

So..  you could test BITS to the EV server from a client (or server) in several of your "good" remote locations and compare with the "bad" locations.  Lookup (on MSDN or shout and I'll write the instructions) BITSADMIN and you'll see you can create say a 200 Mb file on the EV server, and pull it down using BITS.
