> We use an exponential decay function to smooth performance monitoring. This dates back to the early days of the project when we were taking samples frequently and everything looked like noise. Now our performance is a bit more steady and we take samples about every 5 seconds. I think we need to update some parameters so that finer-grained performance characteristics show up in the monitor. This is critical for the next wave of Accumulo performance improvements.
