Maybe RTFM is the better answer, but maybe just a quick reminder...  each
instruction is executed in four quarter-cycles (Q-cycles).

If you weren't using the PLL, your 10 MHz would execute 2.5M instructions
per second.  With the PLL, you still get 10M instructions/second.

[maybe a little oversimplified, but just enough to jog your memory]  :)
