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

Language	Vehicle	Reason
GoLang	Tesla	The future, but want somebody I know to buy one first
Haskell	Batmobile	Looks awesome but you'll never figure out how to drive it
Java	Hummer	Uses way more resources than is strictly necessary
Perl	Classic Mini	A classic that has influenced many cars, but not practical for 2015
PHP	Fiat Multipla	Ugly, nobody wants to be seen driving this
Ruby	Smart Car	Practical design. Will get you around the city fast, but not great on motorways
Python	VW Golf	Solid. Reliable. Middle of the road.
