Freefilesync (shown running two jobs separately below to two spaces) is always slow syncing to the ‘private user space’ compared to the ‘Public share’ SMB space, especially when the files are relatively small but present in hundreds or thousands of copies as in pictures or audio or document files. You can improve sync by using the ‘Public’ space when possible and/or use a different sync program such as Dsynchronize (also free). The fastest method is to store small fragmented files in a zip container that has low o no compression and that can be done by following the link below using Teracopy (also free).
