VSTS virtual user limit
I am new to VSTS and I am planning to use this tool for performance testing of a web application.
I need to load the application for millions of transactions
the queries I have
1. Is it possible to have huge amount of load , generating from single machine. (which i guess NO , then what are limit of load that can be generated from a single computer)
2 Is there any standard guideline available for load testing with VSTS
Any help to above mentioned point is greatly appreciated
Re: VSTS virtual user limit
With VSTS you can drive very large loads, how large certainly depends on the size/configuration of your machine, network badndwidth etc. as with any other load test tool. Internally at Microsoft we have been using it across many teams including Sharepoint, MSIT, SQL, MS Live properties etc. Specifically as an example, for AdCenter, a 12 hour production test run drove about 3.63 billion requests at an average requests / sec of 84,248.
VSTS uses a controller agent architecture that allows you to deploy the controller on a separate machine and install agents that will drive the load for you to be able to scale the load.
For your second question, I would point you to a blog by Ed Glas who has provided a lot of good insight and knowlege on tool usage/best practices etc. at the link below.
Hope this helps.
