For those who are experiencing slowdown:

I don't have enough down-and-dirty knowledge of Linux to draw any worthy conclusions, but here's an anecdotal observation for a knowledgeable person to check out.

I installed the latest HE2007 today and observed a performance improvement, UNTIL I created a symbolic link so I could view my Root files in File Manager. Upon doing that, the entire system slowed down noticeably, something akin to what I see described by other users. Got rid of the links and the system returned to reasonable performance again.

For what it's worth...
