• Two of my favorites: code::dive conference 2014 - Scott Meyers: Cpu Caches and Why You Care: [VIDEO] CppCon 2014: Mike Acton "Data-Oriented Design and C++": [LINK] They're mostly about C++ and cache aware/data oriented programming.

• Here is a good visualization on access speeds for each level of cache, then main memory. Now take the main memory access time and essentially double it (for your state of the art SSD's today) and that's the access speed. [VIDEO]

• Cache associativity, conflict miss. You have too many memory addresses mapping to the same cache lines all being used together at the same time. Scott Meyers had a very good talk which contained this information: < [VIDEO] >
