load-testing

How to you simulate > 120 concurrent users using a Load Test Framework such as JMeter? Real concurrency, as far as I understand, would be possible if I would use 120 servers or 120 CPU cores. How did/do you test your web application or service with real conditions? I have found JMeter to work fine, but I generally use is across 4-5 PC's to get the most accurate results. Although you may believe 120 concurrent users may be difficult to simulate from a single PC, you have to realise that in a real work scenario, 120 simultaneous users will not be accessing the server at exactly the same time,

Please forgive my ignorance as I'm a jmeter noob. My webservice accepts JSON objects so I was able to write a rudimentary test where I create an HTTP Request with a JSON object in the "Post Body" portion of the http request. Anyway, what I want to do is have the HTTP Request choose a different JSON object from a csv file or some other input mechanism so that I can randomize the types of queries that are being run during the load test. Is there a way to do this? The closest is probably using variables (section 4.11 in the user manual) but I have a feeling that's not how variables are used. A

I am now load testing a website through jmeter from my machine. But I want a real world scenario , so can ip aliasing or ip spoofing be used by jmeter which will look like requests are being sent from different ip addresses.? Yes it can, see property Source IP address: : http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Request Note that you must use HTTPClient implementations.

I've been trying to use bees with machine gun without success. As far as I understand, this is just a fabric script that uses AWS to create EC2 instances (bees) in order to perform distributed load tests to a target (website). These are the steps I took: . Went to AWS IAM and created a new user and assigned to a group that has admin permissions: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "*", "Resource": "*" } ] } . The creation of this user gave me an aws_access_key_id and and an aws_secret_access_key. . I used these credentials to create a .boto file where I put

I am running a load test from VS 2008 on my asp.net web application. The thing I notice is that for some of my pages Average Page Time is around 20. Does this mean it takes 20 seconds for the server to render the page before it sends the request? Or is it simply 20 seconds until the whole page is fully loaded on the client's browser? Does this statistic take Network Type into an account; so say that I change from 52kbps to 1.5mbps, is this statistic supposed to change? Another thing is - my Average Response Time is 0.21, whilst some pages have Average Page Time at 20. Why is it so different?

I am currently in a need of a Load test for a web-solution, which requires for a user authentication in Homepage (Welcome Page). When I seek for the POST SignIn parameters which are passing along with the login credentials using FireBug in FireFox, i found out that Password, TenantName, UserName, __RequestVerificationToken are the parameters which are passing along with their values for a successful login. I needed to simulate this process using the JMETER. Therefore i have made a HTTP REQUEST (Visit Login Page) to Navigate to the page using JMETER, which successfully work. Within the HTTP
