The fitness figure is very useful. If you get a fitness of zero, it means there is a drastic problem with your settings.

For example trading periods of 17:00 to 24:00 when your data was 8:30 to 15:00

Or 3 months of data (not a good idea) and filter of > 500 trades.

The #C/us ration is the calculations required per system. If this is high, for example >100 GSB is finding it hard to make systems.

Likely you have wrong settings or a difficult market.

Also see Top/diag if you have a fitness of zero.

Speed by machine.

GSB admin only.

This gives you the total speed of all workers on a specific machine.
