I also ran a benchmark of equals versus identical on my own server. I found the difference to be
surprisingly significant (average of 15% across multiple executions of the script). Just for kicks
I had it compare int to float speed as well and that came up to roughly 40% faster in favor of int
(in equal/identical comparisons - no idea how they perform otherwise), and had it compare ==/=== to
!=/!== and came up to negligible difference (averages out to 0). Here are the results over 100k
iterations - if you want to know exactly what comparisons were done let me know:
