This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance. order by c. c_ytd_payment: 10.00

I then analyzed performance during the benchmark ([active benchmarking]), and used other benchmarks to confirm findings. Also microbenchmarks, which often stress-test the system, will suffer the largest losses. This shows the system-wide syscall rate. In more detail: ## 1. Linux 4.14.12-virtual 05:24:52 PM 0.00
