To perform the test, I'd just use 'time':
test.cc:
int main()
{
int a = 1 + 1;
}
test.pl:
#!/sw/bin/perl
$a = 1 + 1;
# time bash -c 'for x in {1..100}; do ./a.out; done'
real 0m0.167s
user 0m0.029s
sys 0m0.138s
# time bash -c 'for x in {1..100}; do ./test2.pl; done'
real 0m0.435s
user 0m0.154s
sys 0m0.247s
So...I've proved that in my specific environment, C is (~3x) faster
than Perl at adding 1+1...Now as far as what tests you want to
implement, that's up to you and your specific needs.
