Timing stuff in jupyter

Difference between %time and %%time in Jupyter Notebook - Stack Overflow

when measuring execution time, %time refers to the line after it, %%time refers to the entire cell
As we remember¹:
- real/wall the ‘consensus reality’ time
- user: the process CPU time
  - time it did stuff
- sys: the operating system CPU time due to system calls from the process
  - interactions with CPU system r/w etc.

Where’s your bottleneck? CPU time vs wallclock time ↩︎

Nel mezzo del deserto posso dire tutto quello che voglio.
