I wonder if they, maintainers of maxima, would regard this as a bug...
I'm pretty sure the piecewise functions are NOT borrowed from maxima. It
probably gets called because there are some inequalities concerning the
symbolic ring.

Impressive. Thanks.
so, most stuff is happening in maxima and in _subs_,

Hi Sage developers,
Since I posted my request to urgently vote on the modularization PRs, the
big revert (https://github.com/sagemath/sage/pull/37796) was merged into
Sage 10.4.beta4.
The modularization PRs have now been re-created (thanks, Julian, for your
help with this).

For another data point, on an ubuntu laptop:

Wall time: 99.1 ms

sage: version()
As I already told Marc, one should use "pytest" rather than "sage -t" - for
obvious reasons: Sage has very own testing system,
and one should not expect it to be able to test non-Sage code.

Hi,
I get
sage: f = piecewise([((0,1),1)])
sage: time f(0.1)
CPU times: user 135 ms, sys: 4.23 ms, total: 140 ms
Wall time: 146 ms

sage: time f(0.2)

This is painfully slow. Is this normal?
