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?
