It's not slightly faster, it can be an order of magnitude faster.
Example: a listen loop which handles disconnections through exceptions. This isn't stupid but it's not very efficient.

You are correct, I was somewhat disingenuous with _slightly_ faster. It is lots faster but lots faster in error cases, which from a philosophical angle is still absurd.
As long as you use your exceptions for "bad shit" (uncommon error conditions or completely unexpected failures or returns) then I still strongly believe that the performance comparison is silly.
