Why is configure.py slow? How long does its execution take?
\TestPackage asks LaTeX if a package is installed so what has this to do
with the OS?
It may be a problem with the way it is implemented, but the fact is that here
configure.py needs >5s
to complete.
Oh my god, they killed Kenny!
The \TestPackage mechanism already existed before I joined the LyX team and I only take care that we
test for all package we need. Every call asks LaTeX for a single package which takes a few
milliseconds. For MiKTeX there is now a way to ask LaTeX only one time for all packages in a list.
This saves time and is used by the LyX for Windows installer.
However, this feature is not yet in TeXLive and I doubt it is worth it to act here to gain 3
seconds. I mean the configuration is only executed after an installation and then only a few times a
year.
But if you really like to, you can reduce the amount of \TestPackage but then its purpose is
somewhat lost I think - to give users a feedback what packages are used by LyX and if they are
available. What we should do perhaps is to add the info for what a package is needed. Tehn the user
can safely ignore packages for a feature he won't use and he gets the info what feature will not
work because of missing packages. What do you think?
