Dynamically Typed has a new posting today with a few opinions from Harry about the state of current OOP performance in PHP.

In OOP and Performance, he talks about OOP as a trade off: increased "developer performance" through better modularity / re-use vs. slower processing, based on the extra runtime lookup overhead objects introduce (compared to the equivalent collection of functions + variables).

The basic thread running through this new post is that you can't really get the best of both worlds most of the time - either you get the speed or the cleanness of code. Now, I know there's those out there that are claiming they can do both, but the benchmarks might just tell a different story...
