One thing you can do to speed things up is the following. Click menu View - Preferences, switch to the Imaging tab. Click option "Store covers in external files" and enter "0" in the edit box next to it. Press OK. OrangeCD will prompt you to compact the database, which should be done before the new setting takes effect.

The result of the compacting will be that your database will become <10MB in size, and all the pictures will be stored in separate files. And, yes, it will be much faster - practically as fast as it was when database was empty.

In future, try to avoid adding large cover images to the database. It is what makes database huge and slow. If you really want to, use external storage option as described above.
