Hi,

For now, I only see 2 possible explanations:

• you wrote your own feeder/iterator that can become slow at some point,
• your machine is not suited for load testing: either it's not powerful enough, or there's something that can suddenly eat all the CPU, like an antivirus.

Would it make sense?
