Improving python import speed on a yocto-based embedded linux system

I'm working on an application that uses the checksumdir application to validate a couple of directories on boot, after which the normal boot process will proceed. However, we have found that it takes around ~6 seconds to import checksumdir which is increasing our overall boot time.

I've tried importing using importlib but that takes around ~9 seconds to do the same import. Is there a quicker way to do an import?
