An initial investigation has begun on the possibility of upgrading from PHP 5.3 to PHP 5.4. Benchmarks are very promising, but a security enhancement we currently using with PHP 5.3 (Suhosin) is not yet available for PHP 5.4, so the team is debating whether to carry on without it, as well as estimating the performance penalty introduced by this patch. More improvements have been made to Ganglia and Graphite.
