If someone has a few months to spend in the Scheduler ... Note that with the new non blocking FFI implementation (I don't know when it will be in production, the 64 bits port became more important than non blocking FFI, so we inverted the priorities, probably in a year or 2), the VM could show more than 100% cpu usage if using FFI. > > Thank you Sven. > > Esteban A.
