Given the realtime GC is not done nobody really knows. However, the design goal is to have the GC interrupt time to be linear to the stack of your go-routine (with small constants). Thus you should have at least some control over event latencies through program structure. Like I said earlier, there is significant interest inside Google to make it possible to write really low latency services in Go. I personally think 15 usec is reasonable to ask for.
