What is the current recommended flags to build "the most efficient" SBCL for x86_64 on Linux? Is "--fancy" enough, or will I be missing out on some neat optimizations available on latest Intel CPUs (like Skylake-X)?

veckon: 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.

... 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.

Everything beyond that is... Oh, wait. The one who originally asked already left. Nevermind.
