Linux 2.6.30's best five features
Linux's changes may not be as big from version to version, but they tend to be more thoroughly tested and stable. What most users will like in this distribution starts with a faster boot-up for Linux.
1. Fast boot. Older versions of Linux spend a lot of time scanning for hard drives and other storage devices and then partitions on each of them. This eats up a lot of milliseconds because it looks for them one at a time. With the 2.6.30 boot-up, however, instead of waiting for this to get done the rest of the kernel continues to boot-up. At the same time, the storage devices are being checked in parallel, two or more at a time, to further improve the system's boot speed.
There are other efforts afoot to speed up Linux's boot times. The upshot of all this work will be to keep Linux the fastest booting operating system well into the future.
2. Storage improvements.
