What php variables are you running
I have not done any tuning or tweaking to it. You should review each item to best fit your specific use. The following was setup purely from memory at 8pm last night, on to a VM (VirtualBox) using a freshly installed Windows 10 Pro, updating to the latest patches, enabling the IIS (CGI/FastCGI) and installing only the required items; PHP, MySQL, Chrome, Notepad++, WinRAR. I believe my total time spent was about 8 hours. I might have missed a few items, as it was already at the end of my day.
PHP 7.4.11 -
php.ini is attached as
php.ini.txt.
You will need to modify it for your own needs and rename it.
