Sysex Librarian / Any ways to make it faster!

Hello,
I have an old mac that i specifically use to communicate with the machinedrum when making file transfers.
I’ve been searching within the previous threads whether it is possible to make sysex librarian work faster when transfering files!
Anyone has an idea how to speed up the transfer time ?
My settings on the sysex librarian seems good enough.
would be helpful to hear any comments
Or i guess I might need to go back to Mojave and use C6 instead…
Cheers
