Opinion ... I've never found any use for filesystem performance

path for me. As soon as the total data flow approaches the limit
imposed by the filesystem, then anything can cause a pause ... even a
disk drive thermal recalibration or a response to excessive vibration.
Such things cause a momentary delay, and if I'm trying to use the disk
the filesystem I'm using won't matter at all.
