20:12:10dougkveckon: there are no optimizations like what you're implying. "efficient" might, for some user, be "mean and lean" - the opposite of fancy. Disable threads, disable unicode. And disable safety if you want to go recklessly fast. Basically don't think of build options in terms of efficiency though.
20:16:27nyefI, at times, consider mandatory array bounds-checking to be efficient.
20:17:32nyef(What is it efficient at? Finding array-overrun bugs.)
20:20:50nyef... Okay, having checked logs, the main build-time feature toggles that affect time-cost of code running on the target system are threads and unicode.
20:21:51nyefEverything beyond that is... Oh, wait. The one who originally asked already left. Nevermind.
