The level 2 cache is normally much bigger than level 1 cache. The purpose of the L2 cache is to constantly read in slightly larger quantities of data from RAM, so that these are available to the L1 cache. They are slower than L1 cache, but still much faster than regular RAM. It helps in data prefetch to make operations faster. Bigger, the better.

Not really.

You'll see a big jump if you go from say, 256kb to 2MB, but if you're going from say 512k to 1MB you won't really see any increase.

After around 1MB, you don't really see much of an increase at most times, simply because the PC doesn't need to put in that much data.
