Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns                     on recent CPU
L2 cache reference ........................... 7 ns                     14x L1 cache
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns                     20x L2 cache, 200x L1 cache
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 4X memory

# A simple log filter to turn debug logging on and off on a per-module
# basis, when using tornado-style logging.  Note that this works based
# on the module where the log statement occurs, not the name passed to
# logging.getLogger(), so it works even with libraries write directly
# to the root logger.
#
# One drawback to this approach (as opposed to using distinct
# per-module loggers and setting their levels appropriately) is that
# logger.isEnabledFor(DEBUG) will return true even when called from a
# module where debug output is not enabled, so modules that perform
