can you explain more details about this ? .... this is really useful information.

 

Using HTTPS without Keep-Alive Connections. it's up to four times slower than your http connection when not using keep-alive.

do you mean :

using https without keep-alive connection will affect the site speed four time slower and

using https with keep-alive connection will increase the site speed

are that's true ?

so to answer your question, "is it true?", the answer would be yes. This won't probably prove useful for shared hosting accounts but for vps or private server configurations it's a simple change and typically not generated by the hosting company at build.

How do you enable keep alive in prestashop?

You don't.  Keep alive is a web server setting (like apache)
