Applies to:
MySQL Server - Version 8.0 and laterInformation in this document applies to any platform.
Environment: Microsoft Windows using SSD for storage.
Goal
Upgrade from 8.0.17 to 8.0.20 was supposed to fix a known bug (Bug.30766089), but read i/o is slow even with SSD involved.
Need to get the query speed back to the original times.
