Just a note to all you crunchers out there, make sure your PC’s are clean!
Just got a 50% speed increase in Resiel Sieve by moving my PC. Units down from 3h 30m a unit to 1h 50m a unit! 
All of this by moving my laptop from a corner of my room on the floor to a brand new computer workstation (the workstation is that grid metal stuff so nice airflow to base of laptop)
Turns out I’d been throttling myself.
