Speed up Safari/Webkit

[Dronecatcher]

If you don't use Topsites, you can prevent Safari from continually rendering pages you visit as jpg and png files.
Simply turning Topsites off in preferences doesn't prevent it from saving endless screenshots (you can check, they're in: ~/Library/Caches/com.apple.Safari/Webpage Previews).
The png files are full size screen grabs essentially so I imagine Safari is using a fair amount of resource doing this all the time.

To turn off this feature, open Terminal and write or paste:

defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2

press return and quit Terminal.

To reactivate:

defaults delete com.apple.Safari DebugSnapshotsUpdatePolicy

I will try this later and see how much faster it is
I wonder if it would work on my hackintosh?

So long as it has that line in the preference file, it should work.
