Optimizations
Premature and/or over-optimization is often claimed to be a root of most evil in the programming world. However, what to do when optimization IS necessary?
IT Hares discuss certain not-so-trivial optimization techniques. It doesn’t mean that you should use them at all costs (and most likely, you don’t); however, if you do have a reason to optimize – this information may be handy.

Abstract:
Speed of light imposes hard limits on possible latencies of high-volume RAM
Quote:
Even if each bit is implemented by single atom of silicon, 2^90-byte RAM is the largest RAM which can possibly have latencies comparable to modern DDR3 SDRAM.
