timeit() repeats the benchmark a number of times and prints the best time.
Sometimes the run time is slower because of background processes, and the
best time over all loops is a reasonably stable measure of how fast the
code really is. The number of loops is just for your information; tests
th
Thank's both for your answer!
Still I have some questions. Probably I'm not understanding what exactly
means the first data: the number of loops and how should I consider this.
For example if I get the next output for two different functions that I'm
trying to compare:
1 loops, best of 3: 36.4 m
Hi, it's better to use timeit, or in a sage cell, e.g. "%timeit
function(arg)"
The question you were asking deals more specifically what the computer is
doing between start and end of the invocation. "wall time" is like an
absolute clock on the wall, "sys time" the amount of computation the sys
Use timeit to benchmark:
sage: timeit('1+1')
625 loops, best of 3: 729 ns per loop
"man time" will explain real/user/sys if you want to know:
The time command runs the specified program command with the
given arguments. When command
finishes, time writes a message to standard

Some code for doing this was contributed to FLINT a while back. It will
be fast, when we eventually get it incorporated properly in FLINT. It's
been sitting in my inbox for some time and isn't even in the svn
repository for FLINT yet. I don't have benchmarks to give at present,
but I'll let you kn
