As (C) looked like a kernel rebuild, I started with (D) and (E). ## 5. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? I also rewrote this in C and called gettimeofday(2) directly: $ cat gettimeofdaybench.c. Microbenchmark os::javaTimeMillis() on both systems. include <sys/time.h>

This post is targeted towards the questions most often asked by non-technical management who want to get up to speed on what HammerDB is (what it isn’t) and how it can benefit their organization. HammerDB is a software application for database benchmarking. What is HammerDB? Adoption by the TPC. Usage and industry adoption.

HammerDB doesn’t publish competitive database benchmarks, instead we always encourage people to be better informed by running their own. So over at Phoronix some database benchmarks were published showing PostgreSQL 12 Performance With AMD EPYC 7742 vs. Intel Xeon Platinum 8280 Benchmarks . uname -a Linux ubuntu19 5.3.0-rc3-custom

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. SELECT DISTINCT c from sbtest where id between ? order by c. SELECT c from sbtest where id=? HammerDB difference from Sysbench.

You need a business stakeholder buy-in, and to get it, you need to establish a case study, or a proof of concept using the Performance API on how speed benefits metrics and Key Performance Indicators ( KPIs ) they care about. Note : If you use Page Speed Insights or Page Speed Insights API (no, it isn’t deprecated!),
