Very slow with big for loop

[ghost]

for(i=1;i<N;i++)

If N = 2147483647, it is too slow to complete, I have to cancel it. With small N, it is quite fast.

You don't specify what is in the loop, but if you're doing anything that takes a moderate amount of time two billion times, it is going to take a while. Say something takes just a millisecond; do it fifty times and you won't notice. Do it two billion times and it's 40 minutes to complete.

Calc is an interpreted language, not compiled.

On Apple silicon M1 Max:

; N=2147483647; start=runtime(); for(i=1;i<N;i++); print runtime()-start;
166.517041

165.5 seconds.

We have added it as a TODO to consider a JIT for calc in version 3.

See comment 1755671627.

We will close this discussion here and continue it in issue #103 if you wish to post follow up matters.

Thanks for raising this issue.
