Tune performance - multiple threads per flow? #14
Description
As I reach 100% CPU when sending 1 Gbit/s with smaller packets, adding more threads adds more performance (if your CPU has enough cores...).
This was tested with adding multiple flows.
The performance gain is not unlimited, at some point you add more flows and the CPU is not the problem anymore (I think my NIC is not very performant).
The question is how to integrate it in a user-friendly manner:
- I don't like the Idea to add threads automaticly, this should be a decision of the operator
- Add an option to specify how much threads should run in parallel (nice, but one more option)
- Add the possibility to clone a flow
