Thanks Zerof,
Apache 1.3 was fine on windows until we hit is very very hard indeed.
Under these conditions it tended to run out of resources and stop
responding with a long recovery time.
Apache 2 has a very different problem. It does use kernel based accepts
etc, so it seems to handle load very much better. However, mod_php on
apache2 does not seem to guarantee that the same thread well continue to
process the same request. Or at least there is an issue around
stack/heap data.
I managed to show this for definite by using windows system calls to
track the current working thread. During one php request, more than one
thread was active, in sequence. The net result of this on COM was that
static data members got out of line with dynamic ones :-(
I also looked into mod_fcgi to try and overcome the threading problem,
but I found that its methods for managing crashed php processes,
resource allocation etc, were insufficient to maintain a stable system
under extreme load.
The server we use now is TAG.net with uses non-blocking windows IO. It
also uses a queue network for resource allocation so that resource is
targeted to priority pages/services when under high load, this was a
requirement of the sort of web application we are building.
Please - I love Apache! We I have been involved on Unix/Linux/FreeBSD
projects Apache is has been a no brainer. For windows though life is
not so simple :-(
Thanks for your input.

All,
For over a year we have been developing our own web server for running
PHP on windows. We tried Apache 1x and 2x and they did not quite fit
the bill. The first was not stable enough and the second caused
threading problems with our COM library.
I am really interested in what configurations other people have gotten
to work well with PHP on Windows. Especially when they have been
using the COM interface. We use that A LOT, to contact old fashioned
COM stuff and to connect through to .NET.
FYI

Finally, we have done a fair amount of work figuring out how to
optimize COM from PHP (4 in our case) if anyone is interested in this
subject, I would be happy to write a blog article on it.
Cheers
