How to speed up workflow via box api

Hello,

i have one big project for our company where we need to run this program on lot of computers and create report of files and folders which user own. I have code with recursive search for files and folders, which is working fine, but it's too slow, around 2 files per second (2 calls/s). It's possible to speed up process? because this can take 4-5 days to complete with this amount of files and folders. 

Thank you.

Adam
