I think you need to actually time some invocations of ffmpeg and possibly 
profile them (to know where the time is going).

With that many files, are they on local disk or network storage (NFS or CIFS?)?
Is it memory or processor constrained?
How fast can anything open files on this system?

Consider rolling up a program or script that simply opens a file, reads the 
first couple k bytes, and closes it. See how fast that can open all of those 
files. I'll guess it's not much faster than the 4.7/sec.

(There are also other media analysis tools to try, I often use MediaInfo.)

And please don't top-post on this mailing list.

Later,
