While computers are fast, the performance improvements have been spread very unevenly. CPUs have improved the most, with memory lagging significantly behind, and persistent storage even more distant. On the other hand, networks have become much faster than before.

- matt4077 10y agoIs that still true? I would think that the rise of SSD means persistent storage has improved much more CPU, at least in the last decade or so.
- Athas 10y agoNot really, it's just another example of uneven performance improvements. Peak CPU performance has increased massively, but achieving it requires the use of vector instructions (and multiple cores). It is true that the speed of persistent storage has increased faster than sequential CPU performance (but it's still quite far off).
