Consider the multi$-$level memory profile below:

Level $1$: $1000$ bytes $0\mathrm{.}5$t access time

Level $2$: $1000$ KB $1\mathrm{.}0$t access time

Below what hit ratio is this multi$-$level scheme doing more harm than good? Put another

way, at what hit ratio would we be better off with just level $2$ memory? Refer to the hit

ratio example in the slides to get started
