The spinning beachball, a juddery interface, and fans running full pelt: what’s CPU doing in Activity Monitor, and what should you do about it?

How to tell whether an app has a memory leak, what to do about it, and the differences from a kernel memory leak.
How well do USB 3.1 Gen 2 SSDs mix with Thunderbolt 3 SSDs when connected to the same Thunderbolt 4 hub?
In the worst case, an expensive TB3 SSD with a regular write speed of 2.2 GB/s could only write at 400 MB/s when connected via a hub and contending with faster SSDs.
Is the performance overhead of using APFS Encrypted volumes to store sensitive data a reason for not doing so?
From choosing cables and hubs to connecting displays, fast SSDs and other devices. Everything you wanted to know about Thunderbolt.
What happens to read and write speeds of three SSDs connected to the same hub, and working at the same time? Can they exceed the maximum of 3 GB/s?
If you have more than a couple of Thunderbolt peripherals, should you be thinking of getting a Thunderbolt 4 hub?
What happens when you connect two fast SSDs to your Mac and they both write or read at the same time? How do they perform when connected through a hub? And how does it pay to be a winner?
You pay hundreds of $$ for a high-speed Thunderbolt SSD, then connect it to a hub. Will it still deliver the same performance? Maybe not when writing.
