Great to hear, Daniel. It's rare that clients perform benchmarks before moving over

In regards to the performance of PHP and SQL, PHP could technically be faster. Rather than using PHP as a DSO like a huge number of shared webhosts do, we actually run PHP using mod_suphp. I'm not sure if you're aware of the difference between the two, but mod_suphp addresses several pretty significant issues that running as DSO brings with it, and it's really a speed/safety tradeoff. In the benchmarks we've run, the difference is noticeable, but only in the sense that comparing any two numbers would be. We haven't seen any significant performance degradation, nor have our clients, so we believe it's the best choice for us.
As for MySQL, I regularly tweak the MySQL server configuration on each of our servers to obtain the best performance I can. Fortunately, as per your tests, it looks like it's paying off
