A new version using Mach absolute time brings accuracy to a few microseconds, and a Help page. Tests progress well, and continue to make interesting comparisons.

Developing an app to assess the real-world performance of SSDs: initial results from a T2 Mac and an M1 Mac mini are different but there’s no simple answer to which is the faster.
A lot safer than racing through the English countryside in the dead of night, and perfectly legal. So why can’t we get a clear answer to how well an SSD performs?
How fast is the internal SSD? Benchmarks range from around 2.7 GB/s up to nearly 20 GB/s. Which are right? Some new figures, in need of more measurements.
How to connect your M1 Mac in Target Disk mode, avoiding an endless restart loop, and how fast to expect it to perform. Plus more on benchmarks.
How long does it take to write a Signpost to the unified log? Measuring this is essential if you’re going to use them to measure performance.
Apple warns that “Rosetta translation applies to an entire process, including all code modules that the process loads dynamically” – here are some implications.
Your Mac goes all sluggish, you open Activity Monitor, and there at the top of the CPU list is kernel_task, taking 100% or more. Why?
You’re stuck using hard disks with High Sierra or later. Could enabling defragmentation on them overcome the performance problems of APFS?
One solution to running 32-bit apps in Catalina is a VM. Here I assess the performance of Parallels Desktop 15. Is it up to the job?
