Sorry for a delay - I don't have Maple installed at home and had trouble
with connecting to a computer with it remotely.
Yes, it is compiled in C (using Maple command Compiler:-Compile compiling
it in Open Watcom 1.3 supplied with Maple in Windows, or gcc in Linux, I
guess - never had Maple installed in Linux). Changing to not-compiled
version of ES2 (with replacing cs2 in it with s2), gives the following
timing:
time(ES2_not_compiled(10^7));
19.344
It maybe not exactly not interpreted though, because it uses Arrays with
hardware datatype, and operations with them are highly optimized in Maple.
I didn't mean to say that it is relevant to the slowdown. GMP seems to be
also not relevant though - because the integers calculated (primes) are in
32-bit range.
I was wondering about an additional prime - perhaps, he calculated 1 as a
prime?
