[Box Backup] speed up initial sync?

[Dave Thomas]

I am experiencing very long initial sync times with box backup that I suspect 
is due to the extremely high number of small files we use in our application. 
Its not unusual for us to have well over 1 million small files in a dir 
(yea...we need to...don't ask..its some crazy legacy stuff) and while backup 
times have always been long due to all those small files I am seeing initial 
sync times over well over 24 hours with box backup on some of these systems. 
I can deal with the long initial sync times of these systems if I have to, 
but anything longer than 12 hours is eating into 'work time', so I would like 
to speed things up if possible.

My question: Short of tossing cubic dollars at new hardware, is there anyway I 
can speed up the initial sync process?

Thanks for your time,
Dave
