[aspx] Netling + WebSurge (load test)
is a nice little load tester client for easy and quick web testing. It’s open source and on GitHub which is always nice. It’s fun to read other people’s code.
Is a more fully featured tool created by Rick Strahl. Rick is known in .NET spaces for his excellent blog. WebSurge is a quick free download for personal use but you should register it and talk to Rick if you plan on using it commercially or a lot as an individual.
