KAFKA-2663, KAFKA-2664 - [Minor] Bugfixes This has 2 fixes: KAFKA-2664 - This patch changes the underlying map implementation of Metrics.java to a ConcurrentHashMap. Using a CopyOnWriteMap caused new metrics creation to get extremely slow when the existing corpus of metrics is large. Using a ConcurrentHashMap seems to speed up metric creation time significantly KAFKA-2663 - Splitting out the throttleTime from the remote time. On throttled requests, the remote time went up artificially.
