As you might know, on TechNet BizTalk’s theme for September is performance. 


There are many great whitepapers published including Managing a successful performance lab with BizTalk Server 2006 and Get help deploying BizTalk Server with the Best Practices Analyzer (BPA). 


Another great publication is BizTalk Server 2006 Comparative Adapter Study.  This document describes the results of a comparative adapter study-a set of tests that compared each adapter that ships with Microsoft%u00ae BizTalk%u00ae Server 2006 against its BizTalk Server 2004 SP1 counterpart under identical conditions.
