Q: Safari lags when on YouTube
Hey Friends
Since quite some time when I'm on YouTube watching Videos, Safari gets terribly slow, the mouse cursor lags behind, and scrolling isn't responsive anymore. When quitting Safari and reopening YouTube, it's fine for a short period of time, but then safari starts to be unresponsive again.
I'm using Safari 9.1.1, on a late 2013 MacBook Pro Retina, 256Gb, 8Gb, 2.4Ghz
Does anyone have a suggestion?
Thank you for your help
MacBook Pro with Retina display, OS X Mavericks (10.9.2)

Go step by step and test.

Develop menu will appear in the Safari menu bar.
Click Develop and select "Empty Caches" from the dropdown.
