Just to say how I have solved the problem :
- Set the CPU gouvernor to performance with cpufreq-set -g performance
- Use a low latency linux kernel, really simply installed following a tuto
found on the net for ubuntu.
- Add RT priority in the Cpp code (set_thread_priority())
- Reserve a CPU for my

This is probably not the issue, but sometimes I forget to turn the
compiler optimizations on and that can give you a little boost
depending on the code. gcc -O2 ...

Thanks.
There are commercial real-time low-latency OS "out there" that aren't
