The videos from the BizTalk performance talk by me and Ewan Fairweather  has finally got published on msdn.

Instrument your BizTalk Server

Optimizing and verifying your BizTalk Server installation is not an easy thing to do. The documentation is good but very extensive. This presentation aims to guide you through the most important operations you need to do in order to boost the performance of BizTalk.

Performance Optimization Patterns

This session will present architectural, design, and development patterns to improve BizTalk processing performance. "Performance" can be expressed by latency and/or throughput, and this session will cover aspects of both. This will include pipeline and orchestration patterns to increase throughput, reduce latency, and reduce memory usage during BizTalk processing. We will also cover the results from BizTalk CAT recent Perf engagements.
