Stress testing is something that gets very little love in most death mar.., er I mean web projects. It's usually done at the last minute (or not at all), next to no time gets allocated to it, etc. In the past I've picked a tool, installed it on my machine first, hit the home page, upping the concurrency settings. Then I'd write a simple...
What are people's opinions on the best tool for performance testing ASP.NET applications. Specifically we are looking for a tool that could potentially replay IIS logs to mimic production load. Something that hooks into perf counters would also be useful. Ideas? ...
I would like to be able to control the available memory and CPU resources. What kind of tools do you use to do this? ...
I am trying to automate functional testing of a server using a realistic frequency distribution of requests. (sort of load testing, sort of simulation) I've chosen the Weibull distribution as it "sort of" matches the distribution I've observed (ramps up quickly, drops off quickly but not instantly) I use this distribution to generate t...
My team has just developed a website for a client and wants to test that it'll work under the expected usage for 50 simultaneous users. So the plan is to write a test program that will act as 50 simultaneous users. We need this test program to be able to: Be logged in with a cookie. Our session ids are not embedded in our URLs and w...
I am developing a Windows .NET application (WinForms) and I need to simulate a stress test of the database and the application ( more than 100 conections). What tools do you recommend? ...
There are a number of commercial offerings that I've come across but nothing open-source. I realise that you could do something simiilar with JUnit / JMeter but I'm looking for something a bit more specific. ...
In my current project we are testing our ASP.NET GUI using WatiN and Mbunit. When I was writing the tests I realized that it would be great if we also could use all of these for stresstesting. Currently we are using Grinder to stresstest but then we have to script our cases all over again which for many reasons isent that good. I have ...
I'm trying to setup a stress/load test using the WCAT toolkit included in the IIS Resources. Using LogParser, I've processed a UBR file with configuration. It looks something like this: [Configuration] NumClientMachines: 1 # number of distinct client machines to use NumClientThreads: 100 # number of threads per mach...
Hi all I develop a client-server style, database based system and I need to devise a way to stress / load test the system. Customers inevitably want to know such things as: • How many clients can a server support? • How many concurrent searches can a server support? • How much data can we store in the database? • Etc. Key to all thes...
Is there a way to test an application where you simulate a hundred different clients connecting to a IIS server and asking the same data? At the customer where our project is running they have 400 computers and they often do stress tests with all computers. I on the other hand have only got my laptop... (and a development server). (In m...
I am running a Visual Studio Load Test using an Agent on one of our servers. This server has two CPU and I have a licence for the Test Agent to use both. My question is how do I configure the Test Agent service to use the second cpu? ...
Are there any good (preferably free) tools out there? Can they give accurate estimates that reflect production results when the app goes live? ...
This may be the wrong question to ask but, what's the best way to replicate a large load on an asp.net web application? Is there an easy way to simulate many requests on particular pages? Or is the best thing to use a profiler to track a single request and then work out from that if the performance is ok? It would be good to know how we...
I am working on a proposal for my company into purchasing some load testing software. I have to give 2 choices. One of my choices I am proposing is HP(Mecurary) Loadrunner. Is there another program out there that is comparible with Loadrunner? We are looking at using the software to test the performance of the following. C# .NET Templa...
I am tasked with improving the performance of a particular page of the website that has an extremely high response time as reported by google analytics. Doing a few google searches reveals a product that came with VS2003 called ACT (Application Center Test) that did load testing. This doesn't seem to be distributed any longer I'd lik...
I'm just learning the Model / View / ViewModel pattern and it's variations (DataModel / View / ViewModel, or Model / View / Presenter). What I wonder is: if I use this pattern with a WCF service, is the service the Model (DataModel), or do I need a separate Model to encapsulate the WCF service layer?? When I use WCF as DataModel my Vie...
Hi, i have a web server with my web site and i try stress it but i 'don't be able. I think that the problem is limitated number of concurrent connection in xp(Pro). I wrote a simple client in C# for stress: ... for (int i = 0; i < _numThread; i++) { Thread t = new Thread(CallGetHttp); t.Start(); } ... private void CallGetHttp()...
I am load testing my website. The site calls to a WCF service running on the same box using clientCredentialType="Windows". Everything works until I reach a certain load (which is not even very high), then I get the following error: System.ServiceModel.Security.MessageSecurityException: The HTTP request was forbidden with clien...
