If you have installed the JMRI software on a thumb drive rather than the C: drive, that will cause a massive performance loss. Thumb drives are incredibly slower (10-100 times slower)
This will affect all aspects of JMRI performance.
You should install the JMRI software on your C: drive.
You can then change your User Files Location (see below) so only your user data is stored on the thumb drive. But even then reading and saving will be severely affected.
A better backup/sharing option is to use Dropbox (or similar) to ensure your files are backed up and shareable between computers (you will need to connect your computer to the Internet at least occasionally to backup the files.
This is used so commonly we have prepared a document or two:

This document is equally applicable whether you use your USB drive or your local Dropbox folder for storage (but Dropbox will be around 100 times faster).

The only other thing is that all data is stored in thumb drive, nothing on the "C" drive so I can take the program and data files to another PC if I want to or if the hard drive goes bad I'm safe.
