Because of your comment I checked the latency view and found Go doing quite well, sometimes in the second or third spot. Perhaps I'm missing your point?
Well, in the database access test with multiple queries, Go has an outrageous max latency of 19 seconds, and a stddev of 3x the mean, which is terrible.
This is probably caused by running all the queries in their own goroutine (if you don't know what this is just think of it as a thread - but much cheaper).
This causes the queries to be handled in more or less random order.
We'll fix this for Round 5 ;-)
