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.

Why is it not stupid? If disconnections are part of normal application flow then why would you use an exception?

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.

Maybe I'm missing something. Are you saying that in your application, handling rarely-occuring unanticipated disconnections via exceptions has such high overhead that its results in unacceptable performance?
