Is reflection really THAT slow that I shouldn't use it when it makes sense to? [duplicate]

Answer 1

I've wondered the same thing; but it turns out that reflection isn't all that bad. I can't find the resources (I'll try to list them when I find them), but I think I remember reading that it was maybe 2x to 3x slower. 50% or 33% of fast is still fast.

Also, I under the hood ASP.net webforms and MVC do a bunch of reflection, so how slow can it really be?

EDIT

Here is one resource I remember reading: .Net Reflection and Performance
