Subject: RE: [PHP-DEV] [PATCH] suppressing realpath() with APC + tiny patches
From: JFBUSTARRET@tf1.fr ("BUSTARRET, Jean-Francois")



I know the location is not the best one (IMHO, the PEAR default is not much=
 metter). You can't always have the fastest setup, because there are many=
 other factors to consider (security, ease of management, number of=
 servers/apps to handle, ...).

My point was to evaluate the impact of the patch. Wherever you put your=
 files, it has a dramatic impact on performance, and I wish it (or any=
 similar patch) was part of the standard PHP distribution.

Let's get rid of this useless (when using a cache) realpath call, without=
 having to migrate to PHP5 !
