A concurrency and load testing tool for .NET applications
SeaToad is a library to aid in concurrency and load testing of .NET code. Intended for use by developers or automation testers.
For example, it makes a good second hand if you're trying to reproduce a concurrency issue. You can very quickly generate load representing one or more portions of the suspect code, while manually performing other tasks.
Or perhaps you're worried about the performance of a particular stored procedure with load from an external source. SeaToad can run the stored procedure and the external load for you to locate performance and concurrency bottlenecks.
