Good point. It's just an experiment and Berkely db is the most famous one so I tried it. Now the latest lxmusic cache branch in git uses gdbm instead. The generated db file is twice as large as the one generated by Berkely db, but this is ok since Berkely db itself is much larger than the db file. So I guess the saved loading time in runtime library offsets the wasted time due to larger db file. Please delete the old cache file in ~/.cache/lxmusic.cache and test the latest source code in git "cache" branch. Thanks for testing and commenting.
