How To Diagnose IIS Pushing The CPU To 100% Usage
Nov 15, 2010I have a web server with more than a few ASP.NET sites running on it. Every so often, i notice that IIS is pushing the server's CPU to 100%. The sites share application pools, per .NET version they are running.
What i'm looking for is a way to be able to pinpoint which site it is that is doing this, using some tool. If that tool happened to get down into the code to show it, that would also be nice. If not, i'm happy just knowing which site is causing the issue.
I've already tried using ANTS. However, with ANTS you need to know which site it is, and then have it running and waiting on said CPU-crashing web app. Not perfectly ideal.

W3wp.exe Has High Cpu Usage On Every Request?
Oct 26, 2010I'm running a Windows 2008 server (a VPS with 1GB of RAM), with SQL Server Express and IIS 7 installed. On it I'm hosting a NopCommerce 1.7 website, with a database of around 26 000 products.
Right now I'm the only user of the website (it's in development) and I'm getting rather bad performance from it. To be more specific every time I make a request, the worker process goes to 90-100% CPU usage for a few seconds. Is it me or this is a lot for a 1 user NopCommerce website?
PS: the worker process uses between 100MB-400MB of memory (private working set), and SQL Server with this database, around 160MB.
CPU Usage Relative To Number Of Users?
May 1, 2010My Asp.net application uses 25-30% of the CPU on a test server which has 600 MB Ram on it.
I can see the asp_wb process taking that much percentage of CPU.
This is when I am testing using one user.
How many users can the server afford then without falling over?
Is there a relationship between the CPU Usage and number of user aka if there are 2 users my application will sky rocket to 60% of memory usage?

100% CPU Usage In Xml/xslt Driven Web App - How To Optimize
Feb 25, 2010The web app uses XML from a web service, which is then transformed to HTML using XSLT. The app uses a HttpModule to get the XML using AddOnPreRequestHandlerExecuteAsync.
Classes Used:
XmlDocument - stores the xml.
XslCompiledTransform - stores the transform, is cached in Application.
Asynchronous HttpWebRequest using BeginGetResponse/EndGetResponse
HttpModule with hooked AddOnPreRequestHandlerExecuteAsync events.
I do not want to use the XPathDocument unless there are no other possible optimizations. It would take some complicated code to get all the XML together without the ability to write to the XmlDocument. There is additional XML that does not come from the web service that must also be added to the document.
What Is Normal Memory Usage Of A Mvc Website
Feb 16, 2011I have really tried to Google it but only articles about how to troubleshoot memory issues come up. Before I start to troubleshoot, I would like to know if my web site's memory usage is really abnormal or not.
So it is an asp.net mvc 2 website that runs on IIS 7.5 in production. I guess normal memory usage depends upon traffic, so here are the numbers of an average day:
300 unique visitor
400 visits
3000 page views
I would be really happy to get some idea how much is the normal memory usage for this traffic. Also I would be curious to know how memory usage normally increases with traffic growth.

What am I doing wrong? Am I not disposing any objects or closing any connections here?
Dispose Data Context After Usage?
May 20, 2010I have a member class that returned IQueryable from a data context
public static IQueryable<TB_Country> GetCountriesQ()
{
IQueryable<TB_Country> country;
Bn_Master_DataDataContext db = new Bn_Master_DataDataContext();
country = db.TB_Countries
.OrderBy(o => o.CountryName);
return country;
}
As you can see I don't delete the data context after usage. Because if I delete it, the code that call this method cannot use the IQueryable (perhaps because of deferred execution?). How to force immediate execution to this method? So I can dispose the data context..
