Thanks.

For users testing this, could you please also try larger values in:
/proc/sys/vm/swap_prefetch
Read the current value (it should be in the range of 1-10) and try a value ten
times larger.

It is currently quite gentle in the amount it prefetches, but the code is now
extremely cautious about when to prefetch and I suspect it can prefetch much
more by default, thus intensifying the effect and benefit.

Cheers,
Con
