Comment (by vdelecroix):
Hello,
With #18152, I got a 10x speedup
old version:
{{{
sage: %timeit m^2
100 loops, best of 3: 3.65 ms per loop
}}}
new version:
{{{
sage: %timeit m^2
The slowest run took 69.65 times longer than the fastest. This could mean
that an intermediate result is being cached
1000 loops, best of 3: 336 µs per loop
}}}
Vincent
