Summary0001177: After enable Xdebug PHP works incredibly slow
Description

I have installed apache 2.4 and PHP 5.6 on PC (with windows 10 OS).

After enabling Xdebug php works more than 10 times(!) slower (sometimes more than 20 times) than without Xdebug.

This is php.ini config:

zend_extension = "php_xdebug-2.3.3-5.6-vc11-x86_64.dll"
xdebug.remote_autostart = 0
xdebug.profiler_enable = 0
xdebug.profiler_output_dir = "C:\PHP\tmp"
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_mode=req
xdebug.remote_host = "127.0.0.1"
xdebug.remote_port=9000
xdebug.idekey=netbeans-xdebug
xdebug.trace_output_dir = "C:\PHP\tmp"
xdebug.auto_trace = 0
xdebug.var_display_max_depth = 3
xdebug.remote_connect_back = 0

I've made sure that profiler and autostart are disabled.

Steps To Reproduce

Enable xdebug extension.

Operating System

I'm not sure what to do about this. It's a debugger, it makes things go slower. Although 10x sounds excessive. You can try turning of remote_enable if you're not using the debugger perhaps? Or otherwise, try Xdebug 2.4.0rc1 (out in a few hours) to see if it's faster. In any case, for Xdebug 2.5 I am going to look at some optimisations. There is already a ticket for that. Stay tuned!
