It's like this. You are asking the restaurant to serve you a $1 hamburger and are getting annoyed because the chef is preparing a five course dinner. :) It is fair to want a $1 hamburger quickly, but a restaurant not specialized in serving them might not be able to make one that fast.
In this case, Factor starts a whole integrated development environment, complete with a compiler and gui, but you are just interested in running a small script. One solution is running Factor as a server. It's not bad, I do it all the time and IPC between Emacs and Factor works really smooth. It could work just as well between Factor and Bash. But if you aren't willing to accept that solution then it is hard to solve your problem because Factor's startup time is IO bound. E.g take a look at: #include <stdio.h> #include <stdlib.h> int main(int argc, char *argv[]) { FILE *f = fopen("/home/bjourne/pubwork/factor-orig/factor.image", "rb"); fseek(f, 0L, SEEK_END); long size = ftell(f); fseek(f, 0L, SEEK_SET); char *heap = malloc(size * 3); fread(heap, size, 1, f); long chk = 0; for (long n = 0; n < size; n += 200) { chk += heap[n]; } printf("%ld\n", chk); free(heap); fclose(f); return 0; } On my computer, with the factor.image file hot, running this example takes 140 ms and ./factor -e='' 240 ms. So as you can see, reaching Bash's startup time isn't realistic. Even an image 1/10th the size of the standard one (118 mb) would take roughly 24 ms to load which is still much slower than Bash. Afaik, almost no language runtime can compile and interpret source files nearly as fast as Bash. 2017-02-02 10:09 GMT+01:00 <pet...@riseup.net>: > No need to apologize, as far as I'm concerned we're just discussing :) > Now I hope I didn't sound too rude.
