changing workes on PC

[Blisk]

Is there a difference If I change a worker ONE to WORKER TWO on the same computer in MHash?
Like half of the day it is activer worker ONE and other half of the day is active worker TWO.
Or it is better to have all day the same worker. Because worker one works with low speed and worker two with full speed.

What? I'm not really sure what you're trying to ask.

You generally want to concentrate hashpower in any way possible to reduce overhead costs (bandwidth, mostly).

I am asking if there is difference in hashpower if I use two differend miners of the same pool or if I use one miner?
when mining with two miner each works half day. I assume there should not be any differencies.
