Comment (by kcrisman):
Also,
{{{
/Users/.../sage-5.7.beta2/local/lib/python2.7/site-
packages/sage/misc/sage_extension.py:359: DeprecationWarning: Use %time
instead of time.

}}}
Anyway, it's only the very first time that this is really slow, presumably
due to Maxima starting up. However, there is a brief slowdown.
{{{
sage: time print(len(maxima._commands(verbose=False)))
1926
CPU times: user 0.32 s, sys: 0.07 s, total: 0.39 s
Wall time: 16.06 s
sage: time print(len(maxima._commands(verbose=False)))
1926
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
sage: %timeit print(len(maxima._commands(verbose=False)))
<many 1926 later>
100000 loops, best of 3: 5.09 us per loop
}}}
With 5.6:
{{{
sage: time print(len(maxima._commands(verbose=False)))
1871
Time: CPU 0.37 s, Wall: 16.32 s
sage: time print(len(maxima._commands(verbose=False)))
1871
Time: CPU 0.00 s, Wall: 0.00 s
sage: %timeit print(len(maxima._commands(verbose=False)))
625 loops, best of 3: 2.16 µs per loop
}}}
Testing another command. Old:
{{{
sage: %timeit integrate(cos(x^2),x)
25 loops, best of 3: 21.4 ms per loop
}}}
New:
{{{
sage: %timeit integrate(cos(x^2),x)
1 loops, best of 3: 21.2 ms per loop
}}}
I think this is a non-issue. How often are people going to need really
fast listing of all Maxima commands?
