Slow Load App Pool issue

[Sanjay Pais]

We have a Quad Core Windows 2003 Server with 12 GB RAM
The problem we are facing is that the app pool takes very long to load >
20sec

We have another dual core windows 2003 server where it loads in 5 secs

I have no idea why this is happening.

We noticed that taking out the enterprise library dlls make a big
difference. it loads in 7 secs

What should i do to identify the problem?

Cheers

Sanjay

You might try posting your question to a group with "Windows" (and maybe
"server") in the name. This is a .Net Programming Newsgroup.

I think this is a .NET question Robin.

If so, then I apologize. Seemed like a server performance question to me.
Guess we'll find out if the OP comes back and provides more details.

Yes, a server performance issue regarding a .NET application.

It's the oddest thing. I don't see ".net" anywhere in his posting. Why do
you think it is .Net-related? It's not like there aren't a bunch of postings
accidentally made here for Windows topics. (I'm trying to learn something
here, I'm not being facetious.)

Because it's a technical question (asking about App Pools) and it's posted
in the dotnet.framework NG (rather than the general NG that most of the
wrong Windows posts are made to).

And it mentions "enterprise library" which I believe is a .NET add-on.

Apologies for not checking in earlier. I should have provided more
information in the original post.

We are setting up our new environment with our hosting providers. And we
noticed that the ASP.NET Web site takes really long to load. When comparing
it with load tests we did on our current server it loaded in under 5 secs.

I have tried Process Mon, File Mon to try and identify why the application
is taking so long to load. but have not managed to get very far. We did try
and pull out the Enterprise Library assemblies and that did account for 10
secs.

We have a Load balancer with 2 web servers and a database server. The
website and the code are stored on a SAN.

I tried moving the code to the local disk, using a different user
(administrative priveliges) etc.

I am running out of ideas and any suggestions are welcome.

Let me know if you need anymore information.

Cheers

I must also add that I am timing how long it takes for the login page to
load in a browser both from the server as well as from my desktop after the
Application pool has been recycled.

Scott and Jack,

Thanks for clarifying. I really appreciate it!

Turns out the application blocks were querying clr.microsoft.com which
accounted for ther slow load. Access to the internet is blocked on the
server.
