How does PRTG load balance polling?

I have a two part question.

1. If I have a network with 100 switches and a poll interval of 5 minutes, does PRTG spread the polling of the devices over that 5 minute period? Or does it poll all 100 devices at the same time every 5 minutes?

2. I wanted a Traffic Out only sensor to display a Traffic Out only graph on a map. I am unable to work out how to create a custom sensor with the channels I need so I added a second SNMP Traffic sensor and hid all the other channels in the graphs. Will this result in additional SNMP requests or does it use the one request and data recieved for both sensors?

Thanks

1.) yes, PRTG spreads the polling at startup so that not all polls are made at the same time. After that PRTG will use the set interval. With th e5min interval you should use SNMP v2!

2.) The additional sensor will be an extra SNMP poll.

to avoid that you can use a sensor factory sensor
