Follow-up Comment #14, bug #56752 (project octave):
>From the longitudinal benchmarking, there was a step change loss of
performance from the 3.8.X series to 4.0.X series. Looking at the NEWS file
for 4.0.0, that release featured the addition of a Qt-based GUI and classdef
OO programming. Running today with --no-gui-libs and --no-gui shows very
little difference so I don't think the slowdown is because of the GUI. That
would leave classdef as a large architectural change capable of a 2X
slowdown.
I tried quick test by commenting out the classdef section of
fcn_info::fcn_info_rep::xfind. It was meaningful, runtime went from 14 s to
13 s, but at ~7% is no where near large enough to explain the complete
slowdown. Commenting out the code for packages saved an additional 0.75 s
which is nice, but also not stupendous.
