Hi,
We getting very low perfomance (~1 msg\sec) when receiving messages using Extended Transactional Client on Windows Server 2008 (and R2) x64.

The problem reproduces only in x64 environment, in x86 (32 bit) all works fine.
The problem reproduces easily on different versions of MQ (7.0.1.3, 7.1) and Windows Server (2008, 2008 R2).

Did anyone have such problems with Extended Transactional Client?
How could we resolve it?

In your application, break down the transaction into a list of operations, and dump out timestamps before and after all the operations, to the best accuracy your programming language / runtime environment will allow. Look at the thing (or things) that take up most of the time.. look more closely into that thing (or things).
