It is unlikely to be be faster. Each time you call calibredb, it loads the library. The GUI loads the library once and processes each file in turn.

I am a little startled at the long load times, though. I have quite-large libraries (some number in the hundreds of thousands -- I use it to manage publisher and game dev resources) and even then it doesn't take so long... even running off an external drive.

edit: That assumes you're loading one file at a time. I don't do that and had forgotten you can have calibre add by directory (even recursively). That would not have the same overhead per file, it should behave closer to the GUI upload.
