Comparing a FIFO internally wrapped in mutexes and conds, designed to pass messages, to a single mutex makes very little sense. Of course a channel is slower than one of the bare primitives used to construct it! The proper question to ask is whether your application (or your programmer) lends itself with the CSP paradigm or not, and whether this allows you to write simpler, more robust code. Extremely performance sensitive code will always need to be written In lower level paradigms, using e.g. atomics directly - this doesn't matter for most code though. And to be frank, extremely performance sensitive code is past the capability of Go for quite a few reasons.
