- Resilvers, and scrubs, tend to ACCELERATE (for some reason) over time. Thus, the estimates for "time left" often are unreasonably high at the beginning.
That's because at the start it's working its way through all sorts of crappy metadata, but as things progress, then it is hitting file data blocks where there's a lot more opportunity for many-KB-per-block, which boosts reported speeds. One should ignore reported resilver/scrub speeds until at least ~10% done.
