Not as much "glaring" as a bit conspicuous given the stated strengths of Go. I feel like there's an underlying phenomenon here, many people like to talk about performance but don't actually need it. So any time you do need performance you need to sort through the popular "high performance" implementations and figure out which ones actually perform well in production.
