[tex-k] File searching very slow

[Johannes Kuester]

Hi Karl and Norbert,

as a side note: in the documentation, I missed information on what is
normal/expected/correct output from debugging, and what is an error or
unusual/suspicious/undesired output. Some examples might be helpful here.


I didn't see any notable differences in the logs myself, but wasn't sure.

Yes, slowness is repeatable and persistent. Very much slower: at least
about 20 to 30 times (i.e. a file that takes TeX a few seconds to
process on my laptop takes about a minute on my iMac). TeX itself runs
reasonably fast e.g. when processing text, but slow with any file
inclusion, i.e. it is slow when processing any LaTeX preamble and slow
with any graphics inclusion etc.

~/Library/texmf contains only some empty directories on both systems
("2021" with empty subdirectories "texmf-config", "texmf-var"). All my
local stuff is in "/usr/local/texlive/texmf-local" on both systems. To
mv aside ~/Library/texmf makes no difference. Also to mv texmf-local
makes no difference.

To mv the texmf-dist ls-R results in "file not found" errors.

File system: APFS (on both systems). Unaltered, so case-insensitive
("touch test Test TEST" from a terminal results in only one file "Test"
in Finder).


The problem might have originated with a "system restore" from my
previous machine, i.e. with "Migration Assistant", which restored a lot
of unwanted old stuff. Still I don't see how it could interfere with TeX
in such a way. I had macports on the previous machine, but now homebrew
only, and without any TeX stuff there. And I don't see any interference
in the logs.

I also checked file permissions and ownership, but I don't see any
relevant differences or problems.


Do you have any ideas for any tracing / tracking options to see where
the time is spent?

Any Mac system preferences, security measures which might interfere?

Any problems with zsh instead of bash?
