Another 'me too' from me.
I dont use swap often, or at least I wouldnt think I would. The few
times I do hit swap, it's covered well by prefetch. It covers the
system well after returning from a heavy task, such as a game or
leaving my system to be used as a distributed build system for my
distro. Firefox, Opera, or other big applications if left open, spring
right back, usable almost instantaneously, whereas without prefetch,
there's an annoying and noticable delay.
There doesnt seem to be any compelling arguments against prefetch.
There are a lot of users swearing by it. I maintain packages in the
Arch Linux repositories with prefetch enabled, and i've had no
complaints about it, only praise about how well these kernels handle a
system under load and afterwards.
By concept alone, it's easy to see how swap prefetch can help. Here we
have an implementation in practice, and it's working very well.
