Fortran only half as fast as C++ finding primes

There was a lengthy discussion a while back about this, see

79 Languages speed competition: Can we make Fortran win?

Dear all, There is language speed competition! I just find an interesting video on Youtube, [45 Computer Languages Compared: Which is FASTEST?] The guy called Dave Plummer seems legit. The language speed challenge is simple, given 5 seconds, from 1 to 10^6, find as many as prime number per unit time as possible (correct me if I was wrong). Anyway, the higher the number the faster the language is. Initially perhaps there 45 Language in the completion, now it seems there are at le…

Basically, C++ offloads a lot of the work to compile-time optimisations + the use of bitfields
