Description
currently, they use running counters since the start of the rgw.
should be using a sliding window.
also, the current value is an average, which is susceptible to outliers.
we should add: medain, 90, and 95 percentiles
to have more robust values.
note that this change would require a comment in the release notes, as it changes current behavior.

sliding window or any other stats could be done based on sampling the running counters and doing manipulation on them from the outside (e.g. calculate sliding window based on diffs with the values)
