I'm trying to help you, but this help requires your cooperation. This cooperation requires at least that you understand that a performance problem cannot be solved by changing 3 settings on the web server. Especially not because the web server is only the data provider and can only be as performant as PHP processes the requested data and MySQL provides the data. With WooCommerce, you have chosen an eCommerce solution that is just a plugin for blog software and is therefore unsuitable for running a shop with more than 250 products. A plugin solution can therefore never be as performant as a real eCommerce CMS. If you still want to use WooCommerce, then you either have to tolerate limitations in performance or mask the known performance problems with WooCommece. Masking means that you use the cache plugin including the cache function and ensure that the cache is always warmed up. If you don't warm up the cache, then it doesn't matter what web server you use or what optimization you do. PHP and MySQL are then the main cause of your performance problem because WooCommerce causes an abnormally high server load.
A CDN or CloudFlare does not solve your problem either, especially since, as already mentioned, CloudFlare does not support many of the optimization functions of the cache plugin.

You are known for your clever advice..... After you identify yourself as a LiteSpeed expert and
@Empire wants to follow your smart advice, you should continue your conversation privately. Nobody needs advice from users who just say nonsense.
