True. But I can see no easy way to do it. There should be something like
foo(n):
. . .
if n>100:
add_note('foo() may be faster if you install bar-library.')
and then notebook would check if computation took more than one minute and
if so, print
"Note: The computation took more than a minute. However, we have
suggestions that may help:
- foo() may be faster if you install bar-library.
- . . .
[ OK ] [ Do not show this hint anymore ] [ Disable all hints ]"
But even then the user could be confused if it was actually xyzzy() that
called foo(). So add_note() should take a stack trace.

And this sounds complicated. And there are many places where this will not
help: use sparse matrix, have %cython etc.
