When I am on a heavy task neither cpu reaches 100%. So if cpu0 is 99% cpu1 is 1%, if cpu0 is 38% cpu1 is 62%. I don't run cpufreq. How can I make the processors both work at full speed?

Unfortunately there is nothing you can really do about this if the application you are running is not coded in a way that it can be spread evenly and effectively across multiple cpu or core, just hope the kernel does as best as it can.

Sometimes the processors don't need to run at full speed to get the best performance, or sometimes there is other factors (such as reading from hard disk) keeping them from running at full speed.
