Are there performance differences regarding Pi 1/2/3?

[abraham_lincoln]

Yes, very much so.

Do you have some numbers?

The biggest factor is that each generation of the Pi has gotten a better processor (700Mhz single-core in the original Pi to a 1.4Ghz quad-core in the 3B+). There are also a number of detailed benchmarks out there if you bother to Google it.

Especially in the context of a stratum 1?
