Keybase proof

I hereby claim:

I am bzero on github.
I am bzero (https://keybase.io/bzero) on keybase.
I have a public key ASBr1aoT2gtuuqlbPCnCIhRiqjREacjappXNtcOPh-VvqQo

To claim this, I am signing this object:

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
