I made a test on my console (cmd.exe)
ENV: WinXP SP 3 all updates, PHP 5.2.6 / PHP 5.2.6 non thread safe (NTS)
Intel Celeron 2.4 GHz 1 GB DDR Ram
It showed that the non thread safe is faster than the thread safe
version.
And your point/question is...?
hmmm. can't speak for Mario but reading this caused a few questions to
pop up in my head.
Im an average joe php'er trying to write secure and fast code,
I am aware of threads and processes and the general issues but don't
understand the gritty details of implementing reentrant [C] code (is that
the right word??)
I know that running php in a threaded env is a no-no due mostly to
certain extension being [probably] not thread safe - an uncertainty factor
not suitable for production, at least so I have been led to believe
by comments made by core php devs. (is this [still] true?)
now the question part ...
a, what are the ramifications of having to run php without threading
when we live in a world that's increasingly moving towards
multi-core/multi- CPU systems?
b, Is php not missing out here big time?
d, Will threads ever become recommended in/for php?
e, If threads become the norm, will php code have to be written
differently to account for threads?
f, are there things I can/should be doing to my [production]
systems/software-stacks to leverage extra performance for my php
code from CPUs with multiple cores (and/or machines with multiple
CPUs)?
g, am I worrying about nothing? :-)
