Hi everyone I moved from Debian 7 to 8 but the performance went dramatically down. Performance of previous server in contrast with the recent one is 1 out of 5. Please help me to follow up and find out the problem. Thanks you
We dont have a flowchart for that. But it arent that much parts, just apache, php and mysql when it's a php based website. You should e.g. check if the bad performance happens also with a simple .html file, then with a file that contains just phpinfo() command, that a php cache is installed. It can also be a mysql optimization problem if the site has a mysql database, latest mysql versions perform bad without optimized settings for the ram amount of the server.
