Q3/2025 Maintenance, Q4/2025 Server Maintenance
Description
In testing MariaDB 10.11.13 and 11.4.7 on an Intel single socket server with the InnoDB storage engine and SERIALIZABLE transaction isolation and a scale factor 1 schema it was observed that the overall query set takes 2X the time on 11.4.7 of which most of this is attributed to Q21 that takes 10X longer 50 seconds on 11.4 compared to 5 on 10.11.
