Steps to Reproduce:

This example code does nothing with the parametric type value except to read and return as a result.
Therefore, it was surprising to find a strong difference in the code size and performance for value and reference types.
Is this expected?

See sharplab

Expected Behavior:

Code for value types and reference types is almost the same, performance is almost the same.

Actual Behavior:

Code for reference types is much larger and works 2-3 times slower.
