There is nothing wrong, but you missunderstand something. Lscache is generally faster than without Lscache, but making cache function available is not for free. For the first load it costs performance at your server with several services and ressources like DNS, RAM, CPU.... If your are on shared hosting you must share all ressources with others on the same host and this causes a delay. If you want more speed you must use a dedicated server. And as I already described Cloudflare can also cause a higher TTFB
I checked your site again with empty browser cache. Requested from Germany, so check your own Internet Connection and
the proxy you also use!
