Well, any optimization is a matter of trade-off between memory and CPU. Last years, CPU are not really getting way faster (especially when you consider that Python is usually only able to use a single CPU thread), whereas computers are getting more and more RAM.

I prefer to no pay too much attention to assumptions on the hardware. I prefer to only trust benchmarks :-)
