Performance didn't seem to be affected by adding the metric. Using
ThroughputVsLatency on my MBP (2.3 GHz i7, 16GB RAM) with 35k tuples / sec, 4
workers, 4 splitters, 4 counters, 4 spouts, I saw the following metrics: Avg
latency was 14.3ms with master and 14.0ms with the metric enabled, 99% latency
was 17.0 and 16.9 respectively, and cpu was 3.05 and 3.09 respectively.
Additional details are available for the asking.
