As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? In 2019 myself and others tested kvm-clock and found it was only about 20% slower than tsc.

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 also the case this limitation is at the database level (especially the storage engine) rather than the hardware level.

Having worked with something like 70 large and small companies over the past decade, the business processes and best practices have been tested and work well. So right from the beginning, I’m happy to spend some time getting back up to speed and developing some of my ideas around new hardware capabilities.

Nevertheless in this blog sometimes we do publish performance data to highlight best practices or potential configuration pitfalls and although we’ve mentioned this one before it is worth dedicating an entire post to it as this issue seems to appear numerous times running database workloads on Linux. uname -a Linux ubuntu19 5.3.0-rc3-custom
