Ugh, I just saw this was already reported as bug #54956, sorry about the duplicate.

The unit test in mpfr_matrix_mul_d.cc that attempts to test for performance improvement has a couple of problems, I think it should be removed entirely.

Recently, a unit test in the symbolic package that attempted to measure and compare run time was demonstrated to fail on a CI system. This is because the test inherently assumes the system load will be constant while the test runs. But if other jobs are running at the same time, this can easily fail.

The second problem is that the test relies on the Octave internal function '__octave_config_info__' which shouldn't be used by any code outside of Octave.

If there is a legitimate need for user code to know that OpenMP is enabled in Octave, maybe we can add a documented 'openmp' function or similar to Octave. But since this test should be removed anyway, that seems unnecessary at this point.
