I found a great article on performance testing. The test consists of BTS 2004, BTS 2006 w SQL 2000, and BTS 2006 w/ SQL 2005. This article is a great read. Enjoy.
Well it seems that infosys now requires you to request a copy. I guess to many of you went and downloaded it directly.
The link to request the copy is:

There are a few other papers as well that may be of interest so tak a look at all of them. The one I used was
"BizTalk Server 2006 with SQL Server 2005 takes performance to a new high."
Perhaps I will just post the highlights here and forget about the entire article.
Sorry about the confusion.
This is the 3rd time they moved the resource.
