- shellac 5y agoYes, I would have skipped the fsync thing, which carries a lot of baggage, and concentrate on this. Btw, are you sure those spinning disks are actually flushing to rust? Caches all the way down... ;-)
- marcan_42 5y agoI mean, typical seek time on rust is O(10ms) and these controllers are spending 20ms flushing a few sectors. Obviously rust would do worse if you have the cache full of random writes, though. The problem here is the huge base cost.
