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.
How the E and P cores in an M1 Max chip cope with the heavy system workload after login, but still give the user the scope to run apps immediately.
File data stored towards the periphery of the disk is read and written nearly twice as fast as that near the centre. How to take advantage of this.
How to work out how many threads and which cores are needed to achieve a compression rate up to 1.7 GB/s, and how to estimate power and energy.
