There is much more to v2.6 than just bigger numbers in processor and RAM counts, however. This kernel breaks apart some of the artificial limitations
that have been present in Linux from the beginning, such as the number of addressable devices and total available Processor Identifiers.
If commercial Unix vendors weren't already worried about Linux, they should be now.
Linux has seen wide deployment in datacenters, generally as a Web server or a file server, or to
handle network tasks such as DNS and DHCP, but not as a platform for running mission-critical enterprise applications. Solaris, AIX, or HP/UX
typically get the nod when an application demands the highest levels of performance and scalability. The recent release of a new Linux kernel, v2.6,
promises to change that.
