I'm sorry, I couldn't quite hear you— perhaps more all-caps would help? :-)
The dogmatic 'swap is bad for performance' is justified only because
writing/reading a slow disk is bad for performance.
Tmpfs helps your system avoid disk i/o by giving your system more
flexibility in how it manages all of the available temporary space.
It's something that people who are very concerned with swap impact on
performance should appreciate greatly.

Is all this discussion about performance, optimization and
memory management based on some benchmarks as well,
or it is only a "feels like" flame?
