And a little correction to one of my earlier blocks. There had actually been two gaps of length 1182 in 4119-4120e15:

Tempting to take a higher range that Leif hasn't covered already, but I'll be good for now.

Going to take all of 4300e15 - 4399e15 if that's ok.

17e9 n/sec on 8-thread Xeon E5-2666v3 2.9GHz. sb 24 just a little faster than sb 25.

66e9 n/sec on 48-thread Xeon E5-2686v4 @ 2.7GHz. sb 27 pretty similar to sb 26, and faster than sb 25.

I still have another change to do that should yield a small speedup.

Initially impressive figures until you crunch the numbers, then these Xeons don't look so good:
29.29e9 n/s = 0.30321e9/thread/GHz (your 4000-4001 report)
17.90e9 n/s = 0.77155e9/thread/GHz
66.90e9 n/s = 0.51620e9/thread/GHz

in contrast my i5 @ 4.444GHz using gap3_4 tuned for ivybridge is giving:
20.91e9 n/s = 1.1763e9/thread/GHz
with parameters:
-gap 1250 -delta 200 -sb 24 -bs 16 -mem 12 -t 4
