I believe that my server grew to become slow since i have installed XDebug... So, to be able to test my hypothesis I wish to disable XDebug directly from my server, running Apache2.

I already realize how to disable a module on Apache2, regrettably XDebug isn't showing up like a module.

I have been looking for lessons regarding how to do that however i aren't able to find similarly info.

Help!

Xdebug isn't a module in Apache however in PHP. find your PHP.ini and search for xdebug.

Set xdebug autostart to false
xdebug.remote_autostart=
xdebug.remote_enable=

Disable your profiller
xdebug.profiler_enable=
