cPFence
I am testing cpfence on a test VPS and so far I like it. I love all the option and work you have put into it.
But I have 2 questions.
What are you doing for users who need to add something into htaccess and it's not compatible?
Like security headers. You cannot just copy/paste the code that apache uses.
Is there a site that shows the OLS version to use?
What are others here doing in these situations?
Also for caching, how are you measuring performance?
I use loader.io, and I am finding the test aborts when using OLS and litespeed cache.
With OLS, I also tested hypercache, and I have no issues at all with handling all the traffic.
(My only issue with hyper cache is not adding the line define( 'WP_CACHE', true ); in the config file. It has to be done manually. )
With apache, I use the plugin called Surge. You just enable it and it works. I can through 10k hits over 1 min and it handles it just fine.
