Maybe we can help you better if you tell us why you want to run them "at the same speed".

You can't make the threads run at the same speed as Windows is not a real-time operating system.

The best you can do is to synchronize the start of all of the BackgroundWorkers by setting up a ManualResetEvent. The code at the start of each Worker gets to the MRE and waits for the signal to start. Once you start all of your BGW's, then next statement should be setting the signal on the MRE, releasing the BGW's to do the rest of their work.

Even then, you're not going to get a perfect start. You're sharing the CPU cores with all of the other threads running in Windows! Some or all of your threads may not be running at all until Windows gets around to it. There is nothing you can do about this.
