Yep! I know that and generally I never do such "mad" things, but this
time I did it. I will probably wait for 1.5.0GA until I move to the
1.5.0 version next time.

But could this problem really result in a quadruplication of the run
time for almost all pages? I rather thought that amendments to other
components like Zend_Db or Zend_Controller might have caused the
performance decrease.

This is not so easy to accomplish since my whole application relies on
Zend_Loader. All classes I use should be loaded by Zend_Loader and I
don't really get the point of a Zend_Loader class if it is not
recommended to use it
