Hmm, true. On startup, it only seems to add an extra 1.5 seconds for
Maxima to start, so the list seems to take 15+ seconds.
Okay, it seems to be creating the whole list for tab completion, actually.
I'm used to seeing this slowness, but on my 10-year-old machine with a 1/2
G of memory.
My guess? This line from `maxima.completions??`:
{{{
cmd_list = self._eval_line('apropos("%s")'%s,
error_check=False).replace('\\ - ','-')
}}}
Recall that we also upgraded Maxima in 5.7.beta0, #13364. Perhaps
"apropos" slowed down.
Or maybe the IPython upgrade in #12719 made
{{{
sys.stdout.flush()
}}}
slower, if this only shows up in 5.7.beta1. I'm going to check this
momentarily.
