So every reduction in CPU power will lower overall performance. I also need that another process only uses 30% of CPU and 1024MB of RAM. It can run in the background while you focus on more important things. If you have 16 processes and they're all trying to do work requiring 100% CPU on an 8-core system, the kernel will time-share across the processes; in practice you should expect those processes to get 50% CPU each and the task to just take twice as long.
