I want to test asp.net application for stress, load and performance. Please guide me what free tools should be used for this ? Is there any tool which particularly can be used to analyse individual components, functions and scripts and resources they use ?
View 2 RepliesI'm currently developing a few ASP.NET MVC2/.NET 3.5SP1 web-services that are mostly IO bound (execute a couple HTTP back end calls + DB write per request) and i'm getting really poor load-testing performance.
To make sure it wasn't something in my application, I created a brand new ASP MVC 2 project (project -> new -> "ASP.NET MVC2 Web Application", based on .NET 3.5 SP1), added a "TestController" with the following action:
[Code]....
I deployed this on a dual-core test server, running Win2008 and IIS7, Application Pool set to "integrated mode". I have the following in my C:WindowsMicrosoft.NETFramework64v2.0.50727Aspnet.config:
[Code]....
Just in case, I added the following DWORD key in the registry:
[Code]....
I verified I was able to access my test action from a regular browser and started a load test from another machine on the same network: user load set to 500, no "think" time.
The following is what I observe on the machine running the loadtest after about 8 minutes:
req/s: 5.98avg response time: 78.4 secondsno errors whatsoevernote that the local CPU is 1-2% On the test server, this is what I observe using perfmon:
request current: flat line at 501request execution time: flat line at 1506 ms avg => this makes sense though I don't understand why I see the request coming back after 78 seconds at the other end% proc time avg < 1%request queued as well as all others asp.net v2.0.50727 counters at 0 I don't get it. I believe the expected behavior would be to see about 333 req/s (500/1.5) with a avp response time of 1.5xx seconds...

is it possible to automatically populate a file upload control's file for automated testing and server stress. I have one upload control (that simply brings up the browse and selects the file) and a button that uploads the selected fileupload control's file. Is it possible to give the file upload control a file pather "C:myImage.jpg" and submit the file by pressing the upload butto:
document.getElementById("fileUpload").value = "C:myImage.jpg";
document.getElementById("btnUpload").click();
I know red-gate's ANTS Performance Profiler but it works with source code. I have an ASP.NET web application that is deployed on a remote server. I'm going to test its performance while it is working on the server.
My main goal is to detect what method of what class is slow and then is a bottleneck. Is there a way or a tool?

View 5 RepliesI am currently building a web application that will involve many servers to get it to run efficiently. I am trying to test this web site at home and I have a few computers running the website. To connect to the website I would type this into the address bar http://192.168.0.200:8080 or I would typehttp://192.168.0.201:8080. However when I transfer my site from one computer to another the web browser can no longer read the cookies. I would like to set up a home DNS server and have the computers in my house access the site like this w1.MySite.com and w2.MySite.com instead of http://192.168.0.200:8080 or I would type http://192.168.0.201:8080 so I can test if my cookies are working accross subdomains. how to set up a local DNS server so I can do this?
View 3 RepliesIve got an ASP.net web application and was testing the pages.At the moment I store a variable in the
System.Web.HttpContext.Current.Session[
say the user is authenticated when they have been verified on login.So if the login is successful the authenticated is set to true.This is checked on every page load to make sure they have logged in.What I did was to log in and then the Main Menu page is displayed.I copied the address of this, set the page to goggle's page then pasted the address back into the address bar and the page loaded back up.How can I stop this from happening?Should have some mechanisim to prevent this?If so how.

View 2 RepliesRecently for a class to implement unit test for one of its private methods I used PrivateObject by creating private accessor instead of refelection, to which i received a code review comment as below
"My main concern with Private Object is the use of object[] in constructor. It replaces strong typing enforced by compiler with JavaScript-style run-time error detection.Consequently , personally, I would not recommend it."
Comments above confused me beacuse as per my understanding reflection also needs the object[] to invoke any method.

View 2 RepliesI have a strange situation on a production server. Connection for asp.net get queued but the CPU is only at 40%. Also the database runs fine at 30% CPU.
Some more history as requested in the comments:
In the peak hours the sites gets around 20,000 visitors an hour.
The site is an asp.net webforms application with a lot of AJAX/POSTs
The site uses a lot of User generated content
We measure the performance of the site with a testpage which does hit the database and the webservices used by the site. This page get served within a second on normal load. Whe define the application as slow when the request takes more than 4 seconds.
From the measurements we can see that the connectiontime is fast, but the processing time is large.
We can't pinpoint the slowresponse the a single request, the site runs fine during normal hours but gets slow during peak hours
We had a problem that the site was CPU bound (aka running at 100%), we fixed that
We also had problems with exceptions maken the appdomain restart, we fixed that do
During peak hours I take a look at the asp.net performance counters. We can see behaviour that we have 600 current connections with 500 queued connections.
At peak times the CPU is around 40% (which makes me the think that it is not CPU bound)
Physical memory is around 60% used
At peak times the DatabaseServer CPU is around 30% (which makes me think it is not Database bound)
My conclusion is that something else is stopping the server from handling the requests faster. Possible suspects:
Deadlocks (!syncblk only gives one lock)
Disk I/O (checked via sysinternals procesexplorer: 3.5 mB/s)
Garbage collection (10~15% during peaks)
Network I/O (connect time still low)
To find out what the proces is doing I created to minidumps.
I managed to create two MemoryDumps 20 seconds apart. This is the output of the first:
!threadpool
CPU utilization 6%
Worker Thread: Total: 95 Running: 72 Idle: 23 MaxLimit: 200 MinLimit: 100
Work Request in Queue: 1
Number of Timers: 64
and the output of the second:
!threadpool
CPU utilization 9%
Worker Thread: Total: 111 Running: 111 Idle: 0 MaxLimit: 200 MinLimit: 100
Work Request in Queue: 1589
