some points:
- seems like it still accesses some remote hosts
because it checks if the metadata is up-to-date. It shouldn't
do this the second time you call it, seems like it doesn't
have write access to /var/cache/solv. Please chown the directory
to your uid.
- FL access is slowing it down a bit (FL is the complete filelist).
Even worse is that it had to download the file list for the
chromium repository every time because of the missing write
access.
- Also, I've rewritten the file provides algorithm, so it should
be quite a bit faster now (packages available in an hour). It
now rewrites the cache file after the file provides have been
added.
$ echo n | ( time ./solv up )
rpm database: cached
repo 'fedora': cached
repo 'rpmfusion-free': cached
repo 'rpmfusion-free-updates': cached
repo 'updates': cached

As you can see, if the solv can take full advantage of the
cache (no FL loads), it's pretty fast.
But this really isn't about execution speed, but correctness
of the solver results.
Cheers,
Michael.
