Not sure why reducing the memory should help. Also reducing the number of virtual CPUs has probably little effect as well. The main point in reducing the number of cores and disabling threads is to give modern CPUs more thermal/power headroom to run the fewer CPUs at a higher clockspeed. I doubt you get the same effect on vCPUs. > In OpenBSD, the packet forwarding happens single threaded, so the > performance of your system does not benefit much from the 4 cores. That is not quite correct anymore. -- :wq Claudio
