I'm not complaining - I can't imagine ever wanting to do an integral like this! - but I'm impressed that the Prime is so fast.

The Prime uses the standard C trig functions with standard 'doubles'. That's hugely optimized when you compare it with the decimal, variable precision arithmetic used in newRPL. Also, transcendental functions in newRPL take an extra penalty because of the variable precision, which means no tables with precomputed constants can be used.
And finally, the Prime has vasts amounts of memory, I imagine the algorithm takes advantage of that, while newRPL has to use an integration algorithm that has a very minimal footprint.
So yeah, expect the Prime to leave newRPL way behind on this one case.
