I have magento version 22.214.171.124, When I load any page(cms, search, product page) in frontend then it display blank white page for 5-10 seconds after that it start loading content.
I checked in network section (in browser developer mode), TTFB showing there 5-10 seconds for all page (even a simple cms page which has only static content).
I have also installed Lesti-FPC plugin and all cache are enabled from admin section. And Compilation mode also enabled.
I have two question :
First : How to improve TTFB.
Seconds : How to start to load content, so that no white page display to customer while loading content.
