Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? As I'm interested in the relative comparison I can just compare the total runtimes (the "real" time) for the same result. Here's some experimental approaches I could also explore: Disable tracesys/syscall_trace. us on Ubuntu.

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? Supported Databases. Derived Workloads.

Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? As I'm interested in the relative comparison I can just compare the total runtimes (the "real" time) for the same result. Microbenchmark os::javaTimeMillis() on both systems.

I found the comparison of InnoDB vs. MyISAM quite interesting, and I’ll use it in this post. As the MyRocks storage engine (based on the RocksDB key-value store [link] ) is now available as part of Percona Server for MySQL 5.7 , I wanted to take a look at how it performs on a relatively high-end server and SSD storage.

There are plenty of automated front-end optimisation tools available like modpagespeed and CloudFlare but being a bit old-school and craft-orientated I prefer the ability to control the load order and optimise not only the individual assets but their sequencing as well. Control and branch the loading of CSS and JS. Source: SpeedCurve.

It's challenging for teams climbing the maturity ladder to sift through the many available browser and tool-vendor data points to understand which ones to measure and manage. Treating data as a distribution fundamentally enables comparison and experimentation because it creates a language for describing non-binary shifts.
