L (level) 1 Cache: Cache internal to the CPU; this is the closest
cache the CPU works with
L2 Cache: External the processor itself and often configurable by the
end-user. Generally, this is quicker memory than main store.
Mine shows 256K of a Cache:

I read a book entitled Efficient Memory Programming by Loshin and it
explained a lot of things like this. It also talks about things like
"rolling loops", etc. It was a worthwhile read.
