If they do what you want without making you wait, why even consider changing the filesystem that has been working for years on these machines?

Adding new, bigger disks and new filesystems? Wanting these to be the fastest that is reasonably possible? As for the system that arose the question (again) for me, I've decided to make it ext3, wait for a while as ext4 matures, and convert it later. This interesting possibility made me decide for ext3 (again).

The only thing that can make filesystems fast is buffering in RAM so you'd probably want to match up that increase in disk space with lots more RAM, especially if you use a filesystem that needs it for the improvements it claims.
