yes for two reasons, one relative, one more objective :

- you'll write cleaner and shorter programs with python, so more easy to
optimize
- when you'll really need speed, you'll write standalone web-server with
python, and so a lot more eficient and fast in high trafic.

I've rewrite my "high" trafic web site from php to python and gain 10x of
speed.

Definitely. See here:



Python is place 13, with a speed index of 578. PHP is second last (before
bash) and has a speed index of 197.

Besides that, PHP is a really ugly language - not only to the eye (which is
admittedly a matter of taste), but a friend of mine currently implements a
PHP->C-Compiler had delved deep into the language implementation - and it
_is_ ugly.

I expirienced mayor flaws in PHP 4.0.x, where my declared functions in a
6000 line include vanished from time to time - repeating the request
sometimes solved the problem. That was really nasty.

has somebody tried to run this bench with python2.3 ?

Wow, thanks for link! I will use it as hard proof to lure some of my
friends in using Python! ;-)

This is a little off-topic, but I wish to know how would you turn a
string (or data from a text-file) into an array? For example, maybe
turn each \n into an array.

So a string like:

"This is line 1
This is line 2
This is line 3"

And so when you read that into a list called text text[0] would the
"This is line 1".

Thank you once again.

Re: Python vs. Perl vs. PHP?

Nevermind. I RTFM :-) .

Those benchmarks are doubly useless for the question at hand. Firstly,
they only test command line applications. Secondly, PHP is compiled
without optimizations because the rules state that only the default
configuration can be used. See question 8 of the FAQ:

No, CGI is not a good solution in this case, no matter what the language
(except those perverts who use something like C with dietlibc for this).

The base technology to make web requests fast in Python is something
like mod_python or a Python application server. On top of this I'd
recommend you use a Python web framework, of which there are numerous
ones. The hard part is to evaluate them and choose one.

FWIW I'm currently using Quixote running with mod_scgi against Apache,
mostly because I was fed up with the (lack of) Webware documentation,
which I tried first.

Thanks for the reply! I think I am going to give mod_python a try.
Would I have to be root to install mod_python? Because that's one of
my biggest concerns. I don't have root and I don't want to work on my
windows machine since I am kind of more comfortable working on a Linux
platform.

Basically, most of my Python scripts would just be accessing the MySQL
database and just printing out various data.

Either that or you need to have the privileges to compile Apache +
mod_python and run it on a nonprivileged port (> 1024).

mod_python works on Windows as well. The harder part is finding a web
hoster that will host mod_python apps (pythonhosting. com comes to mind).
I personally find it much easier to learn about system administration
and get my own dedicated server for EUR 39/month.

There is no such thing like a native compiler for PHP. If you're speaking of
the ZEND compiler - AFAIK that one just does some parse tree caching. As I
mentioned before, a friend of mine works on a php->C (and then native, of
course) compiler.

One thing he has to do is to recreate all the library bindings. These are
really slow implemented in PHP - has something to do with the
parameter-passing. And thats something the ZEND compiler doesn't speed up.

Another thing is PHP session mechanism - the simply persist every session to
the filesystem. Sure, there are FS-Caches, but neverless thats not as fast
as imaginable...

And what do you mean by "As fast as Java or C"? There is a huge difference
in speed between these two.

Not that I think that speed matters much here - usually, the bandwidth,
process creation time and database queries are the bottlenecks.

I just picked a few (heapsort.pytho n, methcall.python , objinst.python) tests
and run them on my local machine using 2.2 and 2.3.

The results are that 2.3 seems to need 60-70% of cpu time. Looks good!

time heapsort.python 2.3 80000
real 0m4.779s
user 0m3.540s
sys 0m0.000s

time heapsort.python 2.2 80000
real 0m5.655s
user 0m5.510s
sys 0m0.030s

Mind you: I didn't do a full benchmarking and didn't even try so!

39? Where do you get such a good deal?

15EUR/month on http://lost-oasis.fr i write about them because they make a lot
