Will enabling XDebug on a production server make PHP slower?

Question

The title pretty much says it all...is it a bad idea ? I\'d like to have the enhanced debug messages that XDebug provides on the server.

[edit] Just to make things c

Answer 1

Xdebug is for adding full stack traces to error logs, that is the display_errors ini value, which of course should be Off (even in development I dont want this). It does not allow remote attachment to a debugger unless you enable the remote_attach ini setting. While it is slower, if you have a PHP mystery error like Max memory allocated or Segmentation fault, this is the only way you will see where it actually hapenned.
