What is your best tool for speedup wordpress website?

There are number of free software tools, plugins, and action hooks that will provide a speed boost to the sites visitors.The most difficult part is making sure that the web server itself responds quickly enough to keep visitors happy.

i never liked Wordpress, i build all my companies essentials websites using Notion and notaku.so It can do docs, help desk, blog, changelog and roadmap websites For landing pages i suggest using Framer instead

I use LiteSpeed Cache plugin. Other recommended are: w3 total cache i Heartbeat Control.
