PHP IIS Performance

[Hasan Ceylan]

Hi All,

I have IIS 5.0 Windows 2K SPs and patches sitting on a dual P3 1000
Mhz. box with RAID.

When I do a stress test with MS IIS web stress tool, system cannot
handle more than 50 request / sec. On the other hand asp has no
problem with 5 - 10 times more.

To test it further more I tried to determine where the most of cycle
spent I came to a conclusion that it is actually not the parsing and
running of the script but loading the php module. I tried the same
test with an empty php file results are almost the same which suggests
I think, only thing done is php module is loaded.

I suppose the libraries are being loaded and disposed so much, so it
has something to do something with caching.

Being a big fan of open source community I was dissappointed with
that.

So am I right that
- This is related to initialization of php for each request?
- Is there a way to cache php?

Thanks in advance,
Hasan Ceylan

Hmmm... so a Microsoft application (IIS) running on a Microsoft based OS
(Windows) runs a Microsoft scripting language (ASP) faster than PHP and
you're surprised.

I've never compared performance but I'm sure Microsoft has got stacks of
kludges in their operating system to help ASP along. However, if you were to
compare Linux, Apache and PHP against that configuration I think you'll find
you'll have a different result. ;)

And what about running Apache on Windows, instead of IIS. The .htaccess
method is a killer feature in my opinion that has forced several people away
from Windows for web hosting and development.
