While investigating I found this link regarding wordpress performance.

No clear solutions were presented however the major culprit was identified as preg_replace, which is one of the most heavyweight functions available in PHP. Usually such calls can be changed into for example str_replace or something similar which runs much faster than the “regular-expression string replace”.

This might be worth looking into, but for now I just installed the Zend Optimizer which should help out performance a bit.
