Best settings for these?

I run a 100x server and I'm curious whats better performance for these? I have 5000000 for resources stack size. Whats better on performance making this max stack size per move much bigger or smaller?   "Industrial Conveyor Max Stack Size Per Move Default: 128": 500000, Also should I increase or decrease move frequency for better performance? Thanks for any help  I read the plugin description but didnt understand this part fully. I limit 6 conveyors per player for now

  "Industrial Conveyor Max Stack Size Per Move Default: 128": 500000,
  "Industrial Conveyor Move Frequency Default: 5, Lower = faster moving": 5,

Lower move frequency = faster moving,
Higher move frequency = slower moving.

This controls the time interval of how quickly it's moves items in the conveyors.
