When you increase the number of CPUs, you would expect the time to decreased linearly, if over a certain number of CPUs it stops decreasing or if it decreases slower than linear, it is a bottleneck. This will always happen eventually, but with berry/lefield it happens much sooner. Thank you for reporting back!
