V4.0 IIS 7.0 Integrated Slow / Certain Pages And It Seems To Compile Again Next Time Go That Page Its Very Fast?

Feb 24, 2011

We recently migrated to v4 of .net. We are running iis 7 in integrated mode. When the site first starts its slow. I get that - it compiles for the first time. The odd thing is then we will go to certain pages and it seems to compile again. The next time i go that page its very fast. Nothing exceptional with the second page - but once that is hit the rest of the site is fast.

Configuration :: Slow Initial Page Load Speed And Compile Settings

Dec 8, 2010

Over the last week I've been investigating an issue for one of our clients whereby the initial page load following a deployment of their website takes around 1 minute, resulting in unacceptable downtime for end users. This was happening not only for code deplyments (bin dll's and .config files) but also if there were large numbers of .aspx pages updated. For code deployments it's not an issue, but for aspx updates it is; in this particular scenario, we are making use of a 3rd party content management system (RedDot from OpenText) in which every page of the site is published out as a distinct .aspx page. This means that for this website there's somewhere in the region of 2,400 separate .aspx pages. I realise this isn't an ideal situation but we're working within the constraints of the CMS, and we managed to correlate the instances where the site was unresponsive with App pool restarts, which also corresponded to publications of of .aspx pages.

I found an article by Tess Ferandez [URL] which describes all the reasons why the app pool may restart, and it does seem that if more than 15 .aspx pages are changed then the app pool will recycle and the pages will be re-compiled. Another msdn article [URL] then gave me a few pointers on how to start addressing this problem, and for the moment I've set a flag on the compilation options to prevent batch compilation:

<compilation batch="false">

This means that the initial page load now takes around 6 seconds instead of 1 minute, which is a great improvement. However, I also used the "Compilations Total" performance counter to investigate the number of pages that have been compiled by ASP.NET for my site and was quite surprised that the total number of pages that get compiled peaks at 44, which is odd given that there are 2,400 aspx pages in the site. If the batch flag is set to false, the counter slowly increments by 1 page at a time as you click around on the site; if batch mode is true, the initial compilation takes the number straight to 44 over the course of ~60 seconds. What I'm really struggling to understand is why all 2,400 pages aren't compiled. Does anyone have any inside info on what might be going on as all the documentation I've read seems to indicate that all of the pages should be compiled and this counter should be much higher.

Visual Studio 2010 - Site Upgraded VS08 - VS10, And Now Compile-time Errors Do Not Show Until I Request The Page At Run-time?

Mar 11, 2011

I have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.

MVC: First Access After Some Minutes Slow, Then Every Following Request Is Fast?

Jul 30, 2010

when I access any page of my ASP.NET MVC website first time, then this first request is slow. It needs about 4-5 seconds to load. But every following request to any page is fast.When I wait some minutes or a hour then every first request is slow again. Every following request is fast.

I think that IIS 7 is compiling the code and keep it in memory. After some time it will delete it from memory so it needs to compile it again.What can I do that every first request is as fast as every following request?
(Without precompiling my source, if possible)

AJAX :: Update Panel Fast In Debugger But Slow When Published?

Jan 29, 2010

I know it's not the best practice to do, but unfortunately I created a page with multiple large dropdown lists and have them inside an ajax updatepanel. I found some work arounds using siderite's ajax updatepanel adapter:
http://fastlistadapter.codeplex.com/.

The performance is very good while I am debugging on my machine, but when I publish the site and post it to a win 2003 server the performance drops off almost as bad as when the fix isn't there.


I understand that using a 3rd party fix really isn't supported by most, but is there any obvious reason why debug performance would be much better than published site performance on the same exact code?

Databases :: Oracle.DataAccess.Client Very Slow - How To Make It Fast

When I run my piece of SQL through SQL developer it takes less than half a second with an overall cost of 618 on the explain plan.

When I run the same SQL through .NET via the oracle.dataaccess.client connection it is impossibly slow taking over 5 minutes to run.

What could be causing this and what can I do?

Web Forms :: FileUpload And MaxRequestLength: Why Does Application Know So Fast And Form Know So Slow Of Exces

May 11, 2010

Let's say you set maxRequestLength to the max number (2097151) (units are KB) and use the following code for your OnClick event for your submit button:

int int fileSize = FileUpload1.PostedFile.ContentLength;

if (fileSize < 2000000)//units are bytes
Label1.Text="too big";
else
{
FileUpload1.SaveAs(saveItHerePath);
Label1.Text = "Upload success.";
}

Why when a huge file is attempted does it take a minute to get to the OnClick event on the server? Because if maxRequestLength were set to that value 2000, it would immediately choke if you tried to upload a 500MB file. What is going on here? What are the best practices for using the FileUpload control? Is there a better alternative way of uploading or checking for file size?

Configuration :: Adapter.Update (table) Fast On Development Machine, But Very Slow On Server?

Oct 17, 2010

Using VisualWebDeveloper 2010 on the development machine. All nice and fast.Using VisualWebDeveloper 2008 on the server. Server runs on Windows Server 2008 and has IIS 7.

It looks like that when 'table', a datatabe filled up in C# code behind, is getting longer, then the server (whether running the website on IIS or on the local host of VIsualWebDeveloper2008) is really slowing down. Checked it in debug mode and traced it down to

Adapter.Update(table);

Are there any know issues? Could it be that there is incompatibility between different version of SQL server or something like that? The update works, it is just awefully slow, but only on the server.

What's Standard Practice To Make Sure One Slow Running Page Doesn't Affect Other Pages

Aug 31, 2010

Page A loads very fast; Page B loads very slowly and does some CPU-intensive things on the web server. I noticed that if someone is loading Page B, then Page A also loads slowly - for ALL users. What is the standard practice for making sure this doesn't happen? If multiple users are loading Page B at the same time then Page A is ridiculously slow. Is there an IIS setting, web.config setting, or hardware configuration I could use to make sure that the fast-loading pages aren't bogged down by other pages that need more time to load?

Installation :: Web Page Slow To Start After A Short Period Of Time

Feb 5, 2011

My web site seems to be running quick. I have not deployed my web site yet, so I am the only one using it right now. The problem I have is if I am testing out the site and then I stop using it for a short period of time, when I come back the web site takes about 8-10 seconds to startup again. I did not rebuild the site I just simply stopped using it for a short period of time. It seems like after a short period of time I have to 'wake it up' again. Is this normal? How can I prevent this?

Can Large External JavaScript Files Slow Down The Page Load Time

Aug 4, 2010

When we include Javascript files in our aspx files. either we write all the Javascript code in the Head section of aspx or we link to an external Javascript file.

So when the clinet makes a call to that page. Does that mean that all the Javascript will be loaded on the client side?

If that is the case then does not that mean that it will slow down the loading of page as all the Javascript has to be loaded on the client machine?

Configuration :: Finding Best Practice For Making Sure That Slow Pages Don't Affect Other Pages?

Aug 31, 2010

Page B - loads slowly and needs to do some CPU-intensive operations on the web server.

I noticed that when someone is loading Page B, then Page A also loads slowly. This is even worse if multiple users are loading Page B at the same time. Page A won't finish loading until Page B is done.

Is there a best practice for making sure that Page A can still load quickly? Maybe a config setting or IIS setting that I need to change from its default? With 2 users loading Page B at the same time, the web server CPU usage only gets to 30% so I suspect it might be something I can tweak with the settings.

Get Custom Error Pages Working For Classic ASP With IIS 7 Integrated Pipeline?

Oct 6, 2010

I'm working on a website with legacy Classic ASP pages (being converted to ASP.NET on an as needed basis) and new ASP.NET pages. Use of IIS 7 Integrated Pipeline has been very helpful with our configuration. For example, we were able to get forms authentication working auto-magically with the classic ASP pages simply by configuring the appropriate sections of the web.config file (i.e. no changes were required to the Classic ASP pages, for more info see this).

A colleague of mine believes that custom error pages, as specified in the web.config <customErrors> section, should also be auto-magically applied to the classic ASP pages, but for our website it only works for the ASP.NET pages. Nor have I been able to find any information describing the capability of applying custom error pages to Classic ASP with the IIS 7 integrated pipeline. Is it possible to apply custom error pages to Classic ASP pages per a web.config for an website running under IIS7 with integrated pipeline? If so, how?

Compiler - Automating Finding Compile Errors In Pages?

Jan 20, 2011

I have an ASP.NET website where the pages call a few components in DLLs. I need to change the signature of a method in the component, and short of doing a text search, don't know if this will break any pages or not. IMO, this is the weakness of web programming -- you don't get the benefit of a compiler telling you about syntax errors.

But it doesn't need to be so. Does anyone know if there is a way to run a spider over a website watching for compile errors, or perhaps some tool that would compile all the .aspx files in a folder structure looking for compile errors?

This is merely for syntax checking -- not to actually pre-compile the website.

EDIT It looks like aspnet_compiler is being recommended. I don't use Visual Studio projects for the website -- it's grown over time with my own templating system (back before Master Pages were available). So something that would run aspnet_compiler over all the files in a folder might work...

Strongly Typed - How Much Time To Compile A View

Oct 1, 2010

How much time is spent compiling a view in ASP.NET?Of course I don't expect anyone to give me a number, but I think it's interesting to have an idea of how much time this takes because it could influence the way we implement things.For example, if the time is significant , then I might try to put every result that I need to display in the view in a model class instance (created just to hold the values in such a way that I don't even have to test for objects with null value) and then minimize to the maximum (uh?) the amount of C# code in the view thus decreasing the amount of time necessary to compile the view.Question Does this make sense? Give some thoughts on this one.

Configuration :: First Time Deploying A .Net Application, Get Compile Errors?

Mar 11, 2011

I am using TFS to build my MVC app. I cannot do it because I get lots of compile errors. I am using version 4 of .Net and MVC 2. On the build server I have the .Net framework 4.0 installed. It has been suggested that I should also download the MVC framework as well, but when I look on the net all I can find is this MVC framework; http://mvcframework.codeplex.com/ which does not seem to be relevant and does not work anyway.

One of the assemblies I am missing on the build server is System.Web.Mvc dll.Typical error messages include; "The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)"What do I need to do to fix this?
