How can I adjust the server to run my PHP script quicker? -
i have php script runs on loop x amount of times. code minimal , performs checks. loops run within 1 second of each other , varies.. loops run 8 seconds delay.
how or can adjust/tweak on server (or instruct manager of dedicated server) reduce time between loops milliseconds (or quick possible) rather 1 8 seconds?
thank you!

do use databases, emails, web services, or other similar component? generally, performance of php script dependent on these.
you can use profiling tool xdebug analyse script , find slowest areas of code. can optimise code (e.g. inner loops) improve performance.
