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

If tomorrow all the things were gone,
I’d worked for all my life.
And I had to start again,
with just my children and my wife.

I’d thank my lucky stars,
to be livin here today.
‘ Cause the flag still stands for freedom,
and they can’t take that away.

Python uses the os.py module as a sort of sentinel value to determine where the
stdlib is. It will look in a relative directory first. So if you have a file
structure like…

.
├── bin
│   └── python
└── lib
    └── python2.6
        └── os.py
