I have a couple of general questions (still a newbie in Zephir, not knowing C, and thinking from high-level PHP programmer standpoint). 1. Is this right that Zephir gets much slower (sometimes slower than PHP or not much faster) when it uses PHP functions/classes. (based on https://groups.drupal.org/node/456053 ). How much slower it can be. Or otherwise is it much, much faster when it doesn't use PHP functions/classes? 2. If yes (is slower), is then there a way to use PHP functions in a way to increase performance, f.e. preg_mach, etc. (i think i will never implement on my own some regular expressions in Zephir :) ) 3. Is this tool https://github.com/fezfez/php-to-zephir 100% working/effective? I see ovr user is a contributor - i saw him from time to time on phalcon forums. What about performance after using it. 4. What can be the difference in performance between skillfully optimised Zephir and not optimised Zephir class done by someone inexperienced?
I'am a bit ignorant on the matter so answers to these questions could give me and other (PHP especially) users a better overal picture and comprehend it better.
