Ubuntu, Kubuntu, Xubuntu Ubuntu 13.04 has been released, with the Linux 3.8.8 kernel, a faster and less resource hungry Unity desktop, LibreOffice 4.0, and much more. Ubuntu users will know where to get it, and you're looking for a new installation, have fun. Also fun: UbuntuKylin.

"It's the disk I/O, stupid."

BTW, a note on performance. Pretty much every major serious performance problem I've run into on Linux has involved disk I/O. Whenever you have
- Thrashing due to low memory conditions
- Large programs being read into memory
- Big disk writes
things slow way down. Especially with the latter.

Current "solutions" on Linux seem to revolve around delaying writes for as long as possible. IMO this is doubly stupid, because
a) Eventually the data must be written, and when it is you want the write to be of manageable size.
b) If your desktop freezes, your kernel panics, or your power fails, you do NOT want saved data to be stuck in RAM.

However, I'll readily admit I don't actually have a clue what would constitute a sane, broadly applicable solution; or if such a thing could even exist. If anyone has ideas on that, I'm all ears.
