Zend Framework 2 was just released and Zend offers support for ZF1 for only 18 months from now. I know they were working for new features in ZF2 and then they were going to do some major speed improvements to it since it was 5 times slower than ZF1.
I would like to know how slower is ZF2 than ZF1 from benchmarks or tests you did and not pure speculation.
The latest benchmark I found is from February 22, 2012 and it concludes that ZF2 is 4 times slower than ZF1.
