If your site is running slower with Cloudflare, it is most likely that you have done something wrong. Cloudflare CDN basically just store all your static file on your distributed system around the world so it is faster to server them. However, if your site is slow to reply with html files for example then your whole site will still be slow.
Also 1 thing to note, if your site only serve let's say the US visitors, then just buy a server inside the US and forget about Cloudflare. Cloudflare CDN is only necessary if you want to serve visitors around the world.
THank you for your message. Something must have gone wrong. I'm investigating the issue.
I don't know if its cloudlflare or just server side issue.
I'll take note of that. Sticking on local servers for local audience targets. Thank You.
