System Center, Automation, Powershell and other Thoughts
After having a lot of trouble with Microsoft Server 2008 R2 Standard and very slow transfer rates in a WAN environment,
I wrote about it here: http://www.scapaot.de/blog/?p=311,
today Microsoft came back with a good answer.
The network support team is aware of that error and will bring up a hotfix and kb article in September.
It will be published under ID 2634907.
Nice one! Many thanks Microsoft!

Today we where asked to have a view on some servers where the network performance is really poor.
All servers with this issue are placed in branches using 4mbit MPLS connection.
The network perfomance was round about 4 – 8 KB/s.
Supected where 200 – 250 KB/s.
Also the poor perfomance was shown only using TCP/IP.
On UDP/IP the transfer rate was ok.
So we tested every TCP setting you can ever think of:
But nothing changed the poor performance.
Since we stumbled over a blog, written on January 2011:

And yes, the servers with the issue are all on Server 2008 R2 Standard Edition (RTM or SP1) and have 48GB of RAM.

It’s not a joke:
We removed 16GB of RAM form a server and the traffic was fast.
We remounted the RAM again, and the network performance was poor again…

After that we decided to ask Microsoft about that “Feature”.
I will post a answer as soon as we have an answer.
