### Performance of Loading Fernet/JWT Key Repositories
Lance noticed that it seems that token signing/encryption keys are loaded from disk on every request and is therefore not very performant, and started investigating ways we could improve this[1][2].
I didn't come to a conclusion on if the performance hit was due to the actual reading of something from disk, if it was because we loop through each available key until we find one that works, or if it was because I completely disabled token caching. The obvious worst case in this scenario is trying the right key, last - O(n). This is the approach I was using to preemptively identify which public key needs to be used to validate a JWT [0].
Ultimately, I need some more information/constraints from wxy [1]. Possibly something we can start in anther thread.
