MySQL 9.7.0 vs sysbench on a small server

This has results from sysbench on a small server with MySQL 9.7.0 and 8.4.8. Sysbench is run with low concurrency (1 thread) and a cached database. The purpose is to search for changes in performance, often from new CPU overheads. I tested MySQL 9.7.0 with and without the hypergraph optimizer enabled. I don't expect it to help much because the queries run here are simple. I hope to learn it…
