doc: add some recommendations around slow HDDs

grok-pull is still painful with serialization on an old USB 2.0
HDD, but at least it can finish with flock(1) and disabling
parallelization.  While parallel "git fetch" doesn't seem so
bad, slow seeks are exacerbated by parallel reads in Xapian.
That means some updates can take days instead of hours.  The
same updates take only seconds or minutes on an SSD.
