I have a PHP script which runs on a loop for x amount of times. The code is very minimal and performs checks. Some loops will run within 1 second of each other and it varies.. some loops will run with up to 8 seconds delay.
How or what can I adjust/tweak on the server (or instruct the manager of my dedicated server) to reduce the time between loops to milliseconds (or as quick as possible) rather than 1 to 8 seconds?
Thank you!
PHP code
<style type="text/css">
#check { font: Arial, Helvetica, sans-serif; font-size: 12px; margin-bottom: 40px; }
.red { color: #C00; }
.green { color: #060; }
</style>
