#3440 closed enhancement (fixed)

Split bwauth children more equally

The bw scanners are currently divided into 4 sub-processes that each scan a fraction of the network.

However, the current file sizes are such that the subprocesses make progress unevently. Scanner 2 and 3 are about 2X faster than scanner 1, and scanner 4 is 2X faster than 2 and 3.

This ticket blocks on #1975, though.

this should be as simple as rebalancing start_pct and stop_pct in bwauthority.cfg, no?

the default configuration looks like this:
scanner1: start_pct:0 stop_pct: 12 (12% coverage)
scanner2: start_pct:12 stop_pct: 35 (23% coverage)
scanner3: start_pct:35 stop_pct: 60 (25% coverage)
scanner4: start_pct:60 stop_pct: 100 (40% coverage)

I am testing the following:
scanner1: start_pct:0 stop_pct: 6 (6% coverage)
scanner2: start_pct:6 stop_pct: 25 (19% coverage)
scanner3: start_pct:25 stop_pct: 50 (25% coverage)
scanner4: start_pct:50 stop_pct: 100 (50% coverage)

I'm going to resolve this because we went from 4 scanners to 9.
