Generic speed question (PHP vs.)
Hi,
On a hosted linux environment which I have very little control over, I have a PHP script that takes in X number of floats, performs Y number of simple recursive arithmetic calculations, and produces some output for display to the user.
When I first created the script, 'X' and 'Y' were both in the single digits, and execution time wasn't really important because I was in the micro-second range, so that simple php script was good enough.
Today, the number of variables and calculations are rapidly increasing. I'm still in the sub-second range, but as time goes on I may need to start paying attention to performance.
My site is not revenue producing so I need to keep it on a simple, cheap hosted environment. If I were to rewrite those simple calculations into some compiled language, would I necessarily see substantial performance gains? Or would I see better results looking for a host with better resources (more cores, memory)? PHP doesn't really do multithreading well so I imagine with a heavily recursive application I would see benefit rewriting?
I realize this is a very newbie question. Thanks for any advice.

MAIN(3) 1 MAIN(3)
main - Dummy formain(3)
There is no function named main(3) except in the PHP source. In PHP 4.3.0, a new type of error handling in the PHP source
(php_error_docref) was introduced. One feature is to provide links to a manual page in PHP error messages when the PHP directives
html_errors (on by default) and docref_root (on by default until PHP 4.3.2) are set.
Sometimes error messages refer to a manual page for the function main(3) which is why this page exists. If you discover such a reference,
please file a bug report, indicating the PHP function caused the error that linked to main(3) and it will be fixed and properly documented.
