When looking at strace for various Guile things, I'm seeing a lot of
readlink system calls for directories in the load path, e.g.
Is this not more a side effect of using Guix (the GNU store) than Guile
itself?
I'm pretty sure that, store or not, there is probably not a good reason
Guile is 'readlink'-ing the same directories multiple times. Even if it
were a side effect of using Guix, it appears to be something that needs
to be addressed in Guile.
Any idea what leads to this behaviour?
Hypothesis:
* Guile is searching for .go/.scm files in the load paths
* as part of that this process, it readlinks stuff
(don't know why Guile would need this information though)
* it doesn't cache any of this readlink information, so if
you load N .go/.scm files from the same directory, then the
number of readlink calls is multiplied by N.
Assuming this hypothesis true, a potential solution could be to cache
the readlink information. Whether that's a correct solution depends on
what the purpose of these readlink calls are ...
Best regards,
Maxime.
