ipfw with Windows Server 2008 R2 Standard Build 7601 64bit

[Evgenia]

Hello!
I have a problem with wpt installation on cloud.
Operating system is Windows Server 2008 R2 Standard Build 7601 64bit.
When I try to install ipfw then Windows Server is becoming very slow.
I set Testsigning mode On.
Windows was rebooted.
Then, I installed ipfw + dummynet (like https://sites.google.com/a/webpagetest.o...nstances).
So, OS became very slow.
Second problem related to the end of the test.
I wait end of test during 480 seconds, but page was loaded earlier.
May I get this result if ipfw works uncorrectly?
And what I should do to install properly ipfw?

Same here with Windows 2012 R2 64-bit.
Very slow connection because of the dummynet driver. Tests take ages with driver enabled....

I've tested on Windows 8.1 Pro x64 and x86, both with ipfw+Dummynet enabled. When I run a speedtest on speedtest.net upload is completely dead. 0,1 Mbit on average...
After disabling ipfw+dummynet my upload speed = 200 Mbit.

Traffic shaping is not working correctly.

Lots of errors when I run (as administrator) ipfw.cmd, see errors in reply above. There is definitely some sort of bug in ipfw/dummynet thingy.

@Patrick: Do you know why dummynet isn't working correctly? How can we debug this?

The ipfw+dummynet driver does not work on Windows 2012 R2 64bit as far as I can tell.
