Hello, when You coming to OLS from any webserver, You have plus points, all is faster on Wordpress. Most help you the LiteSpeed free plugin, sending static html files without calling PHP. User webbrowser cache switch on too to 365 days. When you clicking in WP admin menus, its abnormal faster than any one webserver 🙂
When you want it more special settings, that You find in OLS settings (open ols admin port 7800), but aaPanel have own settings set, so can't there change anything. You must install other panel, or install OLS alone with MySQL and Fail2ban, IPtables... Your server will be little faster without any webhosting panels.
My fine tuning settings will be other than You, because I optimised for ultra-heavy loads (Eshops with many 10000-100000 products and everyday updating xml feeds), php memory limit 768-1024MB. I have a gratis Plesk license too, but I don't use it (Nginx with Apache from professionals is slower). I don't know what type WP sites You have. Test all settings nonstop.
