Some computers allow you to prioritize processes; you could try bumping up the process for Scratch on the computer to see if it was any effect (although, last time I tested it out once, it didn't do much for me).

If you use windows...open task manager, go into the "processes" tab find Scratch.exe, right click on it and move your mouse over "set priority". Then set the priority...
I don't know what to do for macs...
Hope this helped!
