 Done! Now your downloads should go substantially faster. This is still a feature in observation. We're not sure the benefits are sufficient, so don't hesitate to let us know in <a href="https://support.chamilo.org/issues/6853">the related issue in Chamilo's tracking system</a>

+<h2><a name="#10.igbinary"></a>IGBinary for courses backups and better sessions management</h2>
+<p>
+<a href="http://pecl.php.net/package/igbinary">IGBinary</a> is a small PECL library that replaces the PHP serializer. It uses less space (so less memory for serialized objects) and is particularly efficient with memory-based storages (like Memcached). Use it for course backups (see <a href="https://support.chamilo.org/issues/4443">issue 4443</a>) or <a href="http://www.neanderthal-technology.com/2011/11/ubuntu-10-install-php-memcached-with-igbinary-support/">to boost sessions management</a>.
