EDIT: Please don't trust in the numbers appearing at the top of this thread. Obviously there were bootloader/firmware issues that needed to be resolved and afterwards Potato performance will be somewhat higher.
Since I didn't find numbers may I ask owners of the device ( @Igor, @TonyMac32 ?) to run 4 quick benchmarks? Two times openssl, 7-zip and tinymembench. Please comment also which clockspeeds and which distro you used (Xenial preferred).
Thanks!
