Visual Studio includes a new load agent product for achieving scaleable load generation. The Team Test Load Agent enables you to configure an arbitrary number of agents that will work together to generate load against a web server or web farm.

Key features include:

        Scale out load generation

        Efficient load generation (1000 users from a typical machine running a typical web test)

        IP Switching for testing web farms. Each agent can be configured to use a range of IP addresses. That way load is distributed appropriately when load testing a web farm.

        Favorable Per CPU licensing (no vUser licensing)

        Performance counters collected on Load Agents and machines under test.

        Data (performance data, perfmon counters, and logs) are rolled up and stored in central SQL Server for analysis

        Load Test Monitor enables monitoring a test in progress

        Run tests from VS or Command Line

        Deployment of test code, reverse deployment of logs/test results

        Parallel distributed functional test execution

        Run a large set of unit and functional tests at the same time

        Agent selection enables matrix testing

        Code Coverage

        Better quality of service: load tests are restarted if the test process exits due to a failure.

        Share test lab hardware with a team

        Multiple clients can submit test runs

        Controller queues runs and manages agents

        Platform for test tools

        Extensible architecture supports third party test types

        Team Foundation Server integration

        Reporting

        Work Item tracking

        Build Server

        Source Code Control

 

There are a couple of articles on our team blog that discuss the load agent:
