This sounds more like you need faster disks or whatever else it is waiting
FOR, not processing power. Over 40% of the CPU is used in waiting on
other peripherals to complete their tasks.

PS: 20% system time is also quite high, that is time spent "in the
kerneL" etc. For instance context switching (switching from one
task to another), but also most I/O is system initiated.
But anyway, you still got about 30% idle time, so the CPU isn't
the problem.
