preliminary numbers on my nvme... -b 6750 is ~5min faster and 11% less bytes written than -e -b 4000...
so pick your poison, if you have excess ram, might as well use it? if not, not really a big deal?
it also looked like I could use less ram than 6750 for bitfield, but too late to try all the numbers below the maximum recommended on the plotting chart
