Hi all,
perfectly fine is not the thing i see when using Iris and LPL .)
Even in a simple scenario with 1 sender and 1 host you will see a lot of
packages lost(>30% for me).
We had the same thing on Micaz nodes using the the default values for
the CCA check. When increasing the CCA check value to 1600 (~10ms CCA
check), the package loss dropped to 1-2%.
I will do some testing and let you guys know whether i can somehow fix it.
