How Can I Mitigate the Performance Overhead of .NET Reflection?

.NET Reflection: A Performance Trade-off

.NET Reflection provides powerful runtime code introspection and manipulation capabilities. However, its performance overhead is a significant consideration for developers.

Performance Bottlenecks

As highlighted by Jeff Richter in his influential presentation, "The Performance of Everyday Things," invoking methods via reflection is substantially slower than direct method calls. Richter's benchmarks demonstrate a performance penalty of roughly 1000x.

Optimizing Reflection Performance

Richter proposes an effective optimization: For methods called repeatedly, use reflection only once to obtain the method's information. Then, assign the method to a delegate. Subsequent calls should use the delegate, avoiding the repeated overhead of reflection. This significantly improves performance.

By acknowledging the performance implications of .NET Reflection and applying appropriate optimization strategies, developers can harness its capabilities without sacrificing application speed.
