Subject: Re: [PHP-DEV] re2c scanner issue
From: dmitry@zend.com (Dmitry Stogov)

Sorry, but I didn't store benchmarks before re2c patch so I can just 
compare PHP_5_3 and PHP_5_2.

Drupal 20% faster
Qdig 2% faster
typo3 30% faster
wordpress  15% faster
xoops 10% faster

Not all the speedup caused by re2c scanner, but it makes significant 
part of it.

Thanks. Dmitry.
