[Vtigercrm-developers] apache log4php 2.1.0

[Prasad]

Adam,

We found most of the time spent in log4php was parsing the xml
configuration etc...
through xdebug even wheng log level was configured to FATAL and log->debug
was invoked.

To avoid un-necessary loss of time in log preference we provided mockup
implementation of log4php and moved library to log4php.debug only for
developer debug purpose which can be enabled via config.performacne.php

Regards,
Prasad
