eneral is a tricky business, and there are a few things to understand:
If you’re using the model for the first time from the hub, you will have to download the weights.
That’s extremely likely to be much slower than any loading method, therefore you will not see any difference
If you’re loading the model for the first time (let’s say after a reboot) then your machine will have to
actually read the disk. It’s likely to be as slow in both cases.
