[Octave-bug-tracker] [bug #56752] Performance slowdown from version 3.2.4 through to current dev branch

[Rik]

Follow-up Comment #36, bug #56752 (project octave):

@jwe: You asked a specific question about convert_to_const_vector.  This
function isn't seen in the profiles of bm.assign.m.  It is seen in
bm.toeplitz.orig.m.  The excerpt from profiling below shows that the function
and its children are taking ~20% of runtime, but most of that is the children.
 The running time for the function convert_to_const_vector itself is small at
<1% of runtime.
