Paul Jones responded to recent Symfony 2 benchmarks to show that the Solar Framework is not as slow as the original tests show and in fact if it used preloading like Symfony 2 does it would be faster..

This is something I have always thought was needed and its something I brought up in Zend Framework discussions back when I was seni-involved.

A big focus of 2.0 it seems is going to be performance and cleaning up the structure to make use of php 5.3 features which is great, I have been preaching the need for ZF to start taking performance as a real concern for a while now.
