Many thanks Patrik. I'll share it with our dev team. I've read it when we have indeed to change our code a bit. If we can distribute the serialization across the processors I'm pretty sure we could achieve around 1.000.000 transactions/s in an 8 cores machine with 4 or 5 actors on each node. Right now I have around 500.000 with 2 actors but increasing the number of actors is not increasing the numbers as we should expect. The network bandwidth is not the problem and I have around 48% of CPU in idle state.
Regards and thanks again for the info.
