Actually finding the method via reflection is the time consumer.

Once you have the method reference, actually invoking it isn’t any different than a regular method.

Although I can't tell you why, it's been my experience that firing a simple method via reflection in both .NET and the JVM is roughly 2x the time of direct calls (or of calls via the 'dynamic' keyword in C#).
