Do fast Thunderbolt SSDs slow down when connected via a Thunderbolt hub? How fast are they when reading at the same time? Does connecting a display affect them?

The M2 Pro and Max gain an extra two Efficiency cores, compared to their M1 equivalents. What effect will that have on their performance, and what of the M2 Ultra?
Just 4 cores and 16 GB of memory were used for the virtual machine to run Xcode and build apps successfully, but only for local testing.
Writing to the Data volume in a VM is dismally slow. Is using shared storage any quicker? What happens when you copy a VM to an external SSD, or to another Mac?
Some threads are set to run in the background, and get allocated to the E cores. Could you run them in a VM, and effectively promote them to run on P cores instead?
All about memory: different types, Unified Memory, Mach zones and the kernel, and how to manage system memory problems.
Three types of Disk Image, encrypted or not, tested when freshly made or used and remounted. So many variations, but only one type of Disk Image can be trusted for writing.
A Mac Studio Max has an SSD delivering up to 7.4 GB/s, and a CPU up to 50% faster than a 16-core Xeon. Why does it write an encrypted disk image at the speed of a slow hard disk?
Lightweight virtualisation has come to Apple silicon Macs. How well does it work, though? Are there any significant limitations?
Both P and E cores are run at different frequencies according to the load on M1 chips. This explores how macOS manages their frequencies and why.
