MariaDB/MySQL was consistently performing much better on the sched/core Git kernel build.

Some of the largest wins on this AMD EPYC 75F3 2P server testing with sched/core Git was with the PostgreSQL database server. Very nice improvements with that tentative Linux kernel code for driving up throughput and lower latency on requests.

The RocksDB key-value store was also seeing consistent improvements with the kernel build from sched/core thanks to this NUMA imbalance change for processors where there are multiple LLCs per node.
