As an experiment I changed the template for a custom column, which changed the last_mod time for every book. The time to send metadata was 12 minutes, or 0.58 seconds per book.
I still get 12 seconds to Get Device Info. The memory picture at that time was:
(all MB)
7860 total/2953 cached/4311 available/1372 free

Processes: 92
Commit (GB) 3/15

Kernel Memory (MB) 407 paged/142 Non paged

The send metadata is again very slow. More than 2 seconds per item. Which is more than double the amount of time it takes for your Nexus. The memory picture remains essentially the same and the number of processes is 91.
