Hi In my server all of the sites that i have in page speed insights they get 97%. The only thing that google suggest me that i must improve is server response time. I am hosting 10 sites that don t have much traffic. My server is a vm with 4 cores 16GB memory and ssd hard disk. With htop the cpu usage are at the most 30% and memory is 3GB All of my sites are joomla Can you suggest me something that it will improve the response time. Is it possible that this is a problem of my provider. Thanks in advanced .
Have you checked the server response time with other tools as well, e.g. the Chrome or Firefox developer tools? How long is the response time and load time of the actual HTML page request (not the whole page with images). And do you use caching in Joomla already and if yes, which kind of caching backend?
I am using memcache and load time of the page is 2.86s dcomcontentloaded is 631ms and document is 466 ms. After a research i did i think that the problem is with initial connection that is 156 ms and ttfb that is 248 ms. In the header of the document i am seeing that cache is not enabled. Am i doing something wrong Cache-Control: no-cache Connection: Keep-Alive Content-Encoding: gzip Content-Type: text/html; charset=utf-8 Date: Tue, 24 Jan 2017 15:40:25 GMT ETag: https://www.mysite.gr/ Expires: Wed, 17 Aug 2005 00:00:00 GMT Keep-Alive: timeout=5, max=100 Last-Modified: Tue, 24 Jan 2017 12:12:26 GMT P3P: CP="NOI ADM DEV PSAi COM NAV OUR OTRo STP IND DEM" Pragma: no-cache Server: Apache/2.4.10 (Debian) Transfer-Encoding: chunked How can i be sure that is nothing wrong on my server setup and the provider?
