Hello,
I have looked into Zend/zend_hash.h and I guess it might be sped up
a little. So far it uses D. Bernstein's hash which is quite fast,
but I think it might be worth replacing it with MurmurHash. I have
tried comparison of speed for them (both as separate C programs, and
compiled into PHP 5_3). Results for REAL keys (collected on running
web server) are at the bottom of this page: http://212.85.117.53/gsoc/index.php?option=com_content&view=article&id=65:hash-functions-for-hash-tables&catid=34:profiling&Itemid=54
speeding up array's does indeed look like a place where one could give
a nice boost to many php applications. however it is also a place that
could create such as many problems of course. so getting this into 5.3
seems a bit unlikely at this point given that the feature freeze is
planned for the 24th.
that being said, on the page i only see benchmarks with artificial
data/code. did you also run some benchmarks again some popular php
applications so see what the real world benefits are in terms of
requests per second?
