I think we (that includes jgt) have understood that. The problem is: verifing the DB creates a certain amount of usage on your disk subsystem because it causes (quite some amount of) disk I/O. if you run several instances of it in parallel it depends on the amount of disk I/O a single instance creates if these several instances run faster linearly with the number of instances.
i.e. if a single instance of the script taxes the disk 10% then running 5 simultaneous instances will drive that up to 50% and run perhaps somewhere in the ballpark of 1/5 of the time. If a single instance taxes the disk already 100% then running 5 instances in parallel will perhaps run about as fast a single instance because you can't tax any resource more than 100%. The disk I/O will be queued (thus serialised again) and this will put a cap at runtime. Perhaps reality is somewhere in between those extremes but you may want to find out beforehand where you stand.
I hope this helps.
