[Question] How do you define 'a TINY repo'?

This git-draw script worked perfectly when there are only ~10 files in the repo.

but once I tried to run ```git-draw``` in a repo containing over 2000 files, it froze - with the ```dot``` process consuming high cpu. finally I had to kill the process after 5 min. 

so, my question is, what's the recommended maximum number of files in a repo?

thank you!
