Go's TLS support should be greatly improved in Go 1.6 thanks to the performance work you referenced by Cloudflare. The licensing issue was resolved and the work was merged 11/10/2016[1] While GC will always carry a cost, great improvements have been made over the last year and continues to be an area of focus for each Go release.

Wait, isn't Go devs said they solved GC latency problems [1]? (from 2015): "Go is building a garbage collector (GC) not only for 2015 but for 2025 and beyond: A GC that supports today’s software development and scales along with new software and hardware throughout the next decade. Such a future has no place for stop-the-world GC pauses, which have been an impediment to broader uses of safe and secure languages such as Go." [2] [1] [VIDEO] [2] [LINK]
