Follow-up Comment #5:

Loading the package with `pkg load ltfat` doesn't take by far as long for me
as reported by others here. So I can't really tell a difference.
But there have been some performance improvements for Octave's (internal)
`stat` function on Windows on the stable branch. I haven't completely
understood the load-path logic yet. But it might be that it is completely
re-constructed after each `cd` which might lead to repeated calls of Octave's
(internal) `stat` function.
Could you please try with a recent build if this is still slow for you?
You could download those from Kai's buildbots:

This is probably something that would need to be improved in core Octave and
not in the package itself. (Although, there might be some mitigating
work-arounds...)
