The raft idle ratio is currently computed as the average of all recorded poll durations. This tends to underestimate the actual idle ratio since it treats all measurements equally regardless how much time was spent. For example, say we poll twice with the following durations: Poll 1: 2s Poll 2: 0s Assume that the busy time is negligible, so 2s passes overall. In the first measurement, 2s is spent waiting, so we compute and record a ratio of 1.0. In the second measurement, no time passes, and we record 0.0. The idle ratio is then computed as the average of these two values (1.0 + 0.0 / 2 = 0.5), which suggests that the process was busy for 1s, which overestimates the true busy time. In this patch, I've created a new `TimeRatio` class which tracks the total duration of a periodic event over a full interval of time measurement. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
