I did. In both cases I was making the same calibredb calls:

• Start content server
• calibredb add <entry parameters here>
• calibredb set_metadata -f publisher 'publisher name' id
• calibredb set_custom <field> <id> <value>
• calibredb set_custom <field> <id> <value>
• calibredb set_custom <field> <id> <value>
• calibredb set_custom <field> <id> <value>
• calibredb set_custom <field> <id> <value>

When "--with-library=n:/libraries/rpg-auto", run time was ~20 seconds per entry.

When "--with-library='http://localhost:8080/#rpg-auto'", run time was ~50 seconds per entry.

It does work. It just works very slowly.

If I can instead do the entire add in one call, or do add and set metadata (built-in and custom) in two calls, I expect I can greatly reduce the time needed.

I'm not an efficiency freak, but I think in a use case like mine it could reduce the run time by a factor of four or five, and could reduce a job that I started last weekend to one day (67 hours runtime down to perhaps 15... not quite 'overnight', but two nights or night-and-while-working).
