The term “site reliability engineering” was coined in 2003 by Google VP of Engineering Ben Sloss , who famously noted on his LinkedIn profile that “if Google ever stops working, it’s my fault.” Shift-left using an SRE approach means that reliability is baked into each process, app and code change.

Testing MySQL 8.0.16 on Skylake with innodb_spin_wait_pause_multiplier

MAY 5, 2019

Fortunately the HammerDB TPC-C/OLTP workload intentionally has a great deal of contention between threads and is therefore ideal for testing spin-locks. So to test I took a system with Skylake CPUs and all storage on a P4800X SSD. In the recent MySQL 8.0.16 model name : Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz. linux-glibc2.12-x86_64/data

I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R. I also applied Six Sigma to capacity planning and presented this at a conference in 2003. I also helped out in the run-up to the 2004 Athens Olympics.

OCTOBER 12, 2018

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. InnoDB is the storage engine that will deliver the best OLTP throughput and should be chosen for this test. . HammerDB difference from Sysbench.

This is mixing concerns and leads to code that becomes strongly coupled, monolithic, hard to write, hard to read, hard to evolve, hard to test, and hard to reuse. In 2003, Gregor Hohpe and Bobby Woolf released their book Enterprise Integration Patterns. Furthermore, the deployment tooling was not ready for SOA.
