Hi Mikus,

as you probably installed previously the Wikipedia activity, my guess
is that the jffs2 gc thread was taking most of the CPU. Sadly, we can
expect greatly reduced overall system performance after any
significant allocation or deallocation of flash space.

This means to testers that before reporting any Sugar slowness, should
be checked with top that the jffs2 gc is not taking cpu.

It's not my area, but I guess this only will be solved when we move to
another fs, hopefully by 9.1.
