changing cache update time

I tried having the simulation program sleep for 10 milliseconds (this would have about doubled the average cache update time) and I ran one of the traces through that I had done previously.

I compared the hit ratios and they were exactly the same which means that simply using the sleep function did not work as I wanted due to the way the simulation program simulates the flows. Basically when the program is sleeping, no packets are being processed so they just wait until the program wakes up and are handled then so the hit ratio is not effected at all by that approach.

I am going to need to look into other ways of simulating the program running on different speed processors.
