Hi Neil,
Redirects are essentially two hit against the Web Server, so there's almost
always a little overhead.
ASP.NET design is very sensitive to how you design your pages or
applications. It's very easy to build very bloated Web apps with ASP.NET if
you don't pay attentition to optimizing your code and deal with things like
minimizing Viewstate, taking advantage of the cache and just plain writing
good backend code. Most of the sample code that Microsoft provides will be
the exact opposite of that <g>...
One thing to remember too is that Page performance is possibly not as fast
as you might expect because there's a ton of stuff happening on the server
to provide the 'POSTback' mechanism, control assignments, event binding etc.
Certainly loads more than a hand coded PHP application. So while individual
page loads may be slower ASP.NET is designed more for scalability and
managing many requests simultaneously rather than providing the highest
performance for individual pages through the Page framework.
Also just for a point of reference: What are we talking about when you mean
slow <g>. Maybe try this site:
http://www.west-wind.com/wwstore/
and see if that seems slow.
If you want to compare apples to apples you should write HTTP handlers which
is roughly the starting point you have in PHP - if you do that you bypass
all of the page handling logic and are on the same level that most other Web
development tools start you out on.
I come from a FoxPro background where I'd written high performing Web apps.
I was also disappointed with ASP.NET at first because it apparently seemed
considerably slower. Part of it was non-optimal design as I mentioned above,
but part of it was just perception. I find that with ASP.NET I often build
way more complex pages than I did with previous tools simply because it's
possible to do so now. I also found once I stress tested the apps, although
the old app was perceived to run faster, it actually didn't scale nearly as
well under load. ASP.NET nearly tripled the load the app could handle before
breaking.
IOW, there are lots of factors that determine performance <g>...
