This program is for mobile and is the fastest on Android, the only one I've seen is a Google Play apk and it's very slow, this one is much faster and I'm talking about Android and mobile cpus, prime95 in AtoM n270 It is slower than this app in a GT-I9195. Greetings.
They were just saying that's one possible way some program without source given could be both fast and accurate to what's already known. As shown a interpretted script can run faster. Also I got that lucas Lehmer app you talked about, when it takes 27-28 seconds for 12711 then yes many programs could run faster. that's why coders use asymptotics.

same exponents as OP, on the only working hardware I have at last check an android phone. I think it has a snapdragon processor, and PARIdroid was edit2: seems my PARIdroid thinks they aren't prime though...
