What I tend > to do is mount with "remount,rw,sync" when heavy load is starting. Really? How does mounting with "-o sync" *improve* performance?

However, I'm curious if usescaes in the embedded world are equally affected by this. > I'm thinking of writing a script that monitors performance, and > remounts as needed, lol. WHAT A HACK. hehe.
