I commenced doing that yesterday. I found the "On Device: No" folder in CC and used Download All.
Observation: It takes about 7 seconds to download each book from the SD Card Cloud Calibre Library to CC. I assume that CC is downloading the book file, the metadata file and adding the metadata to the CC metadata database and coping the book file to the CC library folder.

If you have custom columns "built from other columns" then you can speed this up a lot by installing this calibre plugin. It is available on the plugins manager. Do note that closing calibre or changing libraries will take longer if you install the plugin. How much longer I can't say, but I suspect that it is in the range of 1 second per 1000 books in the library.

I seemed to remember the last time I installed the CC library on the S4 using only the wireless connection that while slow, it was much faster than 7 seconds per book. During one of the stoppages, connected as a wireless device and used Calibre to push a hundred books to CC. This turned out to be no faster than the SD Card Cloud Calibre Library download. about the same or slower rate.

Now this is wrong. I would expect from .5 to 2 seconds/book. Could you send me a debug log so I can look at what might be going wrong?

Random thought: be sure that your phone's wifi connection is as good as it can be. When downloading books using the wireless device connection, network speeds matter.
