Scott Holden shares his experience on .NET Compact Framework performance
It covers .NET Compact Framework in particular, but the advices applies to .NET programming in general. I'm happy to see that "keeping it simple", pays off in performance on .NET CF as well since less code is faster code and fewer objects are better for performance.
DataSets haven't improved much since SP2 though, so I'll continue using CSV DataSets when I need to load datasets fast.
