Aha, you have set here a custom domain user?
If so, this user must have some priviliges such as for schannel. Can you for
the test, set this user to network service or even to SYSTEM?
If the performance is normal now, you should enable some priviliges (such as
logon as a batch/service) for that user using domain security policy editor.

IIS 6 is fast by default. You only need to tune the process pool parameters.
