Subject: An optimization idea
From: karoly@negyesi.net ("Karoly Negyesi")

Hi,

I think zend_hash_compare could get a healthy speed boost in some
cases if first it would check whether the two variables passed to it
are actually the same (because of "reference counting"). Sorry, my C
skills are way too rusty to write the patch which is likely to be just
a few lines long.

Regards,

Karoly Negyesi
