[jira] [Commented] (AURORA-118) Add percentiles to @Timed, or write a new decorator to add percentiles

------------------------------------------

I think this should rather be a feature of {{com.twitter.common.inject.TimedInterceptor}}.

> The @Timed annotation is really nice for 'sprinkling on' instrumentation, but doesn't expose percentiles.  We've seen several areas where a long tail of slow operations caused major performance issues, so spotting these with percentiles would be very helpful.
