Description
After a chat with @rmustacc
Upstairs should record IO times in 6 or so buckets where a bucket is basically a count of IOs that
have happened between this bucket and the bucket below it. I.e. have buckets like:
IO took less than or up to 1 ms
IO between 1 ms and 10 ms
10 ms - 100 ms
100 ms - 1 sec,
1 sec - 5 sec,
5 sec
These stats would start when the Upstairs first starts, and live for the entire time the upstairs is running.
