I was looking for a particular download today on the Microsoft site, and came across a couple of new whitepapers. Check out the Microsoft BizTalk Server Performance Optimization Guide which 220+ pages of performance factors, analytic tools, planning/preparing/executing a performance assessment, identifying bottlenecks, how to test, and optimizing operating system / network / database level settings.
Also check out the new whitepaper on BizTalk 2006 R2 integration with WCF. This is a different paper than Aaron’s WCF adapter paper from last year.
And not sure if you’ve seen this, but the BizTalk support engineers are blogging now and chat about orchestration performance and other topics. The recent post covers singletons, which is of recent interest to folks I know.
