How the number of bundles in /System/Library has risen from Mojave to Sequoia, and why the last 5 years have been so different from the previous 20.

Did you think your Intel Mac doesn’t support the 20 Gb/s speed of USB 3.2 Gen 2×2? It can do, with a little extra hardware support, just as it will a USB4 SSD.
How to connect a USB4 SSD to get better performance from an Intel Mac. Should you buy a Thunderbolt 4 hub, or a Thunderbolt 5 dock? Do any of these live ‘up to’ their claimed performance?
Can you promote threads set to run on E cores so they run on P cores instead? Can you demote threads set to run on cores so they run in the background on E cores?
Why data compression is everyday, and how its performance problems can generalise into tasks of similar structure.
Did you spot the change that didn’t take place as expected in the 15.2 update this week? It marks the end of the Intel era for Macs.
Why pay an extra $600 for a 2 TB internal SSD, after all fast external SSDs are cheaper. Maybe you need to check whether disk performance becomes a rate-limiting factor.
The CPU view in Activity Monitor is the starting point for tuning the performance of software. Here are its virtues, and a few vices to beware of when using it.
Discovering whether using more threads makes a task faster gives insight into where its performance is limited. How to use a VM to investigate this.
A first attempt to describe how macOS decides for a thread which type of core, which cluster, which core, what frequency, and how mobile it should be.
