Subject: Parallel processing
Date: Sun, 27 Mar 2022 21:34:57 +4100	[thread overview]
Message-ID: <20220327213457.11481@sachi> (raw)


"Not every program reacts well to parallel processing, for example conventional (non-SSD) disk IO becomes magnitudes slower if two processes read/write disk at the same time because the disk head needs to keep jumping back and forth between different areas of the HDD to serve multiple processes."

This is not in the zsh topic realm but consideration should be given to avoid hard disk drive thrashing.
