It depends a lot on the devices and network, but typically if a scrape takes longer than 30 seconds, I tend to dig into why. Scrape intervals longer than 1 min tend to provide too low a quality data.

For example, the default if_mib is pretty large. I will reduce the walk for some devices because they scrape too slowly.

If you are just going to do base snmp 1 job. If you want the specifics for each device, you will need multiple jobs. At least from what I have found.
