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

/*
 * Generates a geodesic sphere geometry
 * By default, it is 1x1x1 octahedron, as a first approximation to sphere
 * It will return more sphere-like object if you specify iterations > 0
 * But please keep in mind that it generates (4 ^ iterations) * 8 faces
 * Radius argument overrides default sphere radius (1)
