Hi all. During the RFC doscussion today, the question popped up how the performance of creating closures compares to creating objects. This is particularly relevant for closures/objects created by bootstrap code which is always executed, e.g. when registering with a CI framework.
Attached is a benchmark I quickly hacked up. It indicates that creating objects is about 40% slower on my setup (PHP 5.4.9). I'd be curious to know how it compares on HHVM. In absolute numbers though, creating an object seems to take about one *micro*second. That seems fast enough that we don't really have to care, I think. Anyone want to try? Cheers, daniel
