In our office we are currently evaluating the pros and cons of Magento. Besides all the great features it offers it has a huge con — the performance. We read a lot about it but couldn't find any reliable statements about how fast or slow it really it is. So I put a plain Magento install on my testing machine and gave it a shot...

Suhosin Packages Added For PHP 5.2 and PHP 5.3 (перепечатка)
Per , we have just pushed php52-suhosin and php53-suhosin to our el5-stable repositories for Red Hat Enterprise Linux 5 and clones.
is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections.
The packages pushed to IUS only implement the extension and not the core PHP patches. Whether or not you should use Suhosin is up to you, but you may wish to read the section on their site first.
