Serious rendering performance issue with ASP.NET 2.0

[Spotnick]

I have no idea why, but since I'm trying to recreate my website using
ASP.NET 2.0 I've encountered so many performance issues that I'm about to
give up and continue using v1.1

Seriously, how can a page that is not that complicated be so long to render
locally, it's amazing.

This is the trace info:

22 seconds to load a page showing up a profile & some comments, very small
pages, it's seriously unacceptable, and that is while running in debug on my
local machine (a p4 3 GHz very well equiped), it's even slower on the
website.

It seems every time I use a GridView or a Repeater, I have the same
partner.. I just recoded by forum interface using VS.NET 2005 and it's so
slow that I can't even use it.. loading a thread page takes up to 1 minute
while in ASP.NET 1.1 it can take up to 5 seconds.

Anybody knows why rendering is so slow? I was starting to believe it was
because of my VS.NET' but since the code is also executed on a remote
server, it can't be my VS.NET...

I'm running out of options here... serious problem as it's taking up all the
resources of my Windows 2003 Server.

Thank you.

P/S: Level 1 to 5 is the queries to the database and databinding, which
isn't even why it's slow.

Spotnick,
Sorry your new page is running slow. Easier than porting try to use your
1.1 dll and just reference it on your 2.0 web application untill the
overseers can fix the performance issues.

Good Luck

I wasn't aware you could actually reference v1.1 DLL into an ASP.NET 2.0
application... good thing to know, it might help since I'm running the 2.0
Application as a subdomain of the 1.1 application right now.

Seems to affect only the rendering of databind controls such as the gridview
and the repeater.. some pages simply time out because there is a repeater
with hum, 20 data items in it?

Something that makes me think about going back, but I like the developping
tools and new controls + master pages too much of a benefit to keep on v1.1

I'll try to use the old DLL to make the site fully 2.0 to see if it will
have an impact.. but I see my web server and sql server maxing at 100% too
often these days for a single application.. but all tracing shows it's not
data related but due to rendering.. when I execute my stored procedures, they
run fast.

And I use Enterprise Library latest version, binding the controls with
datatables from strongly-typed datasets.

I know this is a old thread, but my team and I are experiencing this same issue. We have very slow performance periodically throughout the day, the one time we can always count on the slowness is the first hit of the day. After that it seems to speed up dramatically.

We are using Dundas chart and gauge controls along with SQL server, these Dundas items are inside ascx usercontrols which are called dynamicly by the page. Once we created a detailed trace, it appears the slowness if more of a rendering issue than a data/control issue, or at least that’s what it appears.

Did the original poster of this thread ever find a solution?

Here is a sample detailed trace of ours...
