QUESTION
I was in the process of moving repeated arithmetic code into reusable chunks using funcs but when I ran a simple test to benchmark if it will be any slower, I was surprised that it is twice as slow.
Why is evaluating the expression twice as slow

Answered 2020-Aug-03 at 13:28You're creating a new delegate object on every call. It's not surprising that that has a fair amount of overhead.
If you either use a lambda expression that doesn't capture this
or any local variables (in which case the compiler can cache it in a static field) or if you explicitly create a single instance and store that in a field yourself, most of the overhead goes away.
Here's a modified version of your test:
