As one of the people involved in drafting the 7.2 release notes, there was
a fair bit of discussion on this subject while the release notes were being
written. The bottom line is that it's possible to come up with examples
and counter-examples showing why 2xRAM swap is necessary or not.
At the time the release notes were written, the kernel developers were
still working on our kernel's VM subsystem, so the 2xRAM figure was
considered a conservative figure. We also figured that the downside in
most cases was minimal, particularly in those instances where the user is
not that experienced (in other words, newbies are more likely to have
relatively small-memory machines, making the 2xRAM recommendation a small
burden in terms of disk space), and that people that *were* experienced
would have a better idea than we would as to whether their 4-way, 2GB
server box really needs 4GB or swap or not...
