Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

// desire: localStorage and sessionStorage should accept objects
//    in fact they do according to spec.
//    http://code.google.com/p/chromium/issues/detail?id=43666

// but so far that part isnt implemented anywhere.

// so we duckpunch set/getItem() to stringify/parse on the way in/out
// this seems to work in chrome 
//   but fails in FF (cant redefine setItem as a function, it just tostring's it)
