We haven't deployed 1.5PR yet - especially because it's "PR". ;-) Maybe you could use xdebug (1) to identify your bottlenecks? It includes a nifty profiler (2) (beware this really creates lots of data and eats HDD space) which is easy to use. Cheers, Till 1, <http://www.xdebug.org> 2, <http://www.xdebug.org/docs/profiler>
