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

# Shortcut interface to rbenv to quickly pick & switch between Ruby versions.
# Usage:
#   rb <version> [19]
#   rb <version> [19] <command>...
#   rb
#
# A version specifier can be a partial string which will be matched against
# available versions and the last match will be picked. The optional "19"
# argument switches JRuby or Rubinius to 1.9 mode.
