Guess what? Your system has the absolute minimum amount of RAM that's required just to even run Premiere Pro CC 2017 at all. That, combined with the fact that your system appears to have only a single disk (and a spinning hard disk, at that) that's shared by absolutely everything including the OS, programs, projects and media, really skewed your results, especially the CPU-only MPEG-2 DVD MPE Off score and the Disk I/O score - both of which are substantially longer than they should have been.
As a result, your system really needs more RAM and at least one more disk in order to function anywhere near what it's supposed to.
