A useful utility just discovered on CodeProject (made in Italy): A simple VB.NET stress utility for SQL Server 2000.
DBstressUtil (this is the name of the tool) is coded as a Windows Forms VB.NET application and it is designed to work on a SQL Server 2000 database (of course, using the SQL Server .NET Managed Provider classes of the System.Data.SqlClient namespace).
DBstressUtil simulates multiple database users submitting T-SQL scripts (executing stored procedures or simply sending DML commands).
I was thinking to write a tool like this for my project at work but Alberto has arrived first 
Great!
