That is indeed minimal.

Single threading it would be fine, but it would get overwhelmed pretty quickly by a lot of requests and thrash. Also, loading a large metadata file and verifying it would bring it to its knees.

Something you probably need to consider is what the background load for doing that would be, you don't want to have it fall over every 4 hours.
