Your I-7 likely has 4 or more logical processors. The only way to go over 100/N where N is the number of processors is to have 2 or more things (continuously) running simultaneously (like loading a complex web page in a browser). Scripts are going to run as a single stream which will bounce around between processors, giving an average user of 100/N% If you have 4 processors, 25% would be from the script and another 5% handling disk I/O, network, and other Windows tasks. That would result in the 30% you see. Parallelizing script execution is complex and I doubt that it is currently done in QGIS.
