# So interestingly, Signature seems to be twice as fast in Python 3.6 and 3.7 as it 
# was in Python 3.3 and 3.4.  However, it is still 6-18 times slower than the old
# getargspec or getfullargspec that was in Python 3.3.

Python 2.7 getargspec (doesn't use Signature)         : specimen_one (6 args)   : 0.0503
Python 2.7 getargspec (doesn't use Signature)         : specimen_two (0 args)   : 0.0496
Python 2.7 getargspec (doesn't use Signature)         : specimen_three (6 args) : 0.0500
Python 2.7 getargspec (doesn't use Signature)         : specimen_four (13 args) : 0.0652

Python 3.3 getfullargspec (doesn't use Signature)     : specimen_one (6 args)   : 0.0539

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
