SQL Server Tool: SQLQueryStress

This is a free tool, we use it for creating pressures to SQL Server, and testing Performance.

As the screenshot below, I opened 200 sessions, each call 1 query to fill up Tempdb to create Tempdb bottleneck, and loop this 100. I have successfully created Tempdb bottleneck, and with another tool WhoIsActive I can catch the query which is causing bottleneck.

Select top (10000) a.* into #x
from master..spt_values a, master..spt_values b
