As a quick test, I removed the Pack attribute from the Bits array and
got the following speed:
debug0:
Passes: 1108, Time: 5.003198, Avg: 0.004515521, Limit: 1000000,
Count1: 78498, Count2: 78498, Valid: TRUE
Lucretia;1108; 5.003198;algorithm=base,faithful=yes,bits=8
optimised:
Passes: 3286, Time: 5.000592, Avg: 0.001521786, Limit: 1000000,
Count1: 78498, Count2: 78498, Valid: TRUE
