If you're worried about the speed difference between reflection and a hand written command, you're spending your time in the wrong part of the code. Reflection isn't the bottleneck, the database is, by far. Yes, if you speed test the difference between reflection and handwritten, it'll look slow, but such micro-benchmarks are unrealistic of production code. If you look for slowness you'll find it everywhere you look, but if you profile real code you'll find the only slow code that actually matters and you'll find that database IO is the bottleneck generally.
