[Octave-bug-tracker] [bug #59702] Octave 6 slower then Octave 5 ?

[Markus Mützel]

Follow-up Comment #5, bug #59702 (project octave):

When I run the same code in Octave 5.2 and Octave 6.1, `setlocale` is called
24 times in Octave 5.2 vs. 66 times in Octave 6.1.
That difference is probably the main reason for the performance difference
between the two versions.

But instead of trying to reduce the number of times we use the `>>` operator
(which I think is the reason for the slow code path), it might be worth
considering replacing it by a more performant implementation altogether.

Would it be okay if we added a dependency on Google's double-conversion
library?
