Storing ORB Keypoints in file

I need to store ORB keypoints and descriptors inside some file, and am currently using Pickle but it is slow (~10-15 seconds to load). Is there another way that would allow for faster saving and loading?

I tried using JSON before but could not serialize the objects (since they are complicated). Could anyone provide insight?
