Hi. I'll be releasing a major update of YouTube Ratings Preview. Version 3.0 will be ready soon. However, I'm totally unable to reproduce the stutter or low speed issue. It just works very well for me. Would you like to help me beta-test the new version in the following days? The idea is to detect and fix the problem you are suffering. Please contact me at cpr@cpr.name if you would like to help me. Huge thanks!
