[Octave-bug-tracker] [bug #40304] Excessive I/O in load function

[Mike Miller]

Follow-up Comment #7, bug #40304 (project octave):

I can't reproduce the reverse seeks with the current development version (hg
revision 6b787e274eb1). When the sample file is read into Octave, I see many
instances of


lseek(3, 0, SEEK_CUR)


to get the current file offset, but I don't see any reverse seeking and
re-reading of data as reported in comment #1, comment #4, and comment #6. The
file loads in 0.188 seconds for me.

I also notice that the file is not exactly the same format as one created by
Octave, might that make a difference, even though I'm not seeing the same
behavior you are? If you load the file, save all of the variables to a new
file with Octave, and load this new file do you see the same I/O call
behavior?
