Loading speed

[Thomas Scheiderich]

I am building ASP.NET pages and find that it takes about 15-20 seconds to
render the first time it is accessed (this seems to be the case for a page
that really does nothing). I was told that even if I compile the Codebehind
pages first, it won't really help much.

Is there a way to tell the system to go compile all the pages when the
system starts up? The problem is that if it takes that long for each page,
it could look bad for the site when a user hits a page that hasn't been
opened yet and it waits for an inordinately long time.

I was also told that Java doesn't have this problem. I was told that Java
(not sure what their .net equivalent is), renders much faster. Is this the
case? If so, why is that?

Thanks,

Tom.

15-20 seconds seems way too much. Checking... two seconds for a simple ASPX
page with mostyl HTML and a HyperLink control using code-behind.

AFAIK, this will be an ASP.NET 2.0 feature.

The problem is that if it takes that long for each

Quite honestly: In production, this is negligible assuming you're dealing
with hundreds or thousands of users and your application isn't a moving
target. Also, it is a good practice to have a last look at your application
after installing it in production and before releasing it to the public, so
it should be you who sees the delay ;-)

It's much worse for development if you're stuck with a 15 second delay.

I was also told that Java doesn't have this problem. I was told that
Java (not sure what their .net equivalent is), renders much faster.

This is not a question of rendering -- it is code generation. Rendering
takes places once the code generator has produced the page's code.

Is this the case? If so, why is that?

The equivalent J2EE technology is Java Server Pages (JSP). Modern
Servlet/JSP containers offer precompilation.
