One Little (Dynamic Proxy) Victory
Tonight I finished a major change to my proxy method implementation. Coding in IL/Reflection.Emit is always tricky, but sufficient planning made this change virtually painless (one minor IL verification error and another very sneaky error with generic methods I'm still chasing down). I was able to run my performance tests (as they aren't affected by my 2 minor issues) to see if proxy call invocation times went down at all. I thought my new design would work better, but, hey, you never know until you take numbers. The results? The "old" way: total proxy call time was 3.88 seconds (that's the total time of thousands and thousands of method invocations that are actually proxies to handle pre- and post-invocation semantics, not just one call!). The "new" time? 0.37 seconds! That's an order of magnitude difference and my tests didn't have to change one bit (in other words I didn't break the client).
It's the small things in life that make me smile sometimes :)
