There was a recent commit for a similar performance problem, which will appear in 9.6.10.  But that was specifically for cases where there were multiple dropped tables per transaction, and large shared_buffers.

I can't reproduce your single-drop-per-transaction problem.  The replica has no problem keeping up with the master.

Can you share the reproduction scripts, and any non-default config settings?  Especially the setting of shared_buffers (on both master and replica, if different)

Cheers,

Jeff
