Has anyone else tried running vanilla forum on openlitespeed and Cyberpanel, it is completely free.
Openlitespeed is the opensource and free version of (really expensive) litespeed Enterprise. They both are drop in replacements for apache but much faster and use less server resources.
Litespeed and Openlitespeed are almost identical to each other except that Openlitespeed can't re-read apache config files like .htaccess. You have to restart Openlitespeed before it reads the new config which rules it out for shared hosting where all your customers are making changes but it is ideal if you are running your own website(s) and you don't mind restarting the server if you change config files.
I have noticed a big difference in speed compared to apache and even more on reload thanks to LSCache.
