Enduro/X Core

With this announced release [[https://blogs.oracle.com/linux/announcing-the-general-availability-of-the-unbreakable-enterprise-kernel-release-5]] it is highly recommended to move upgrade to this kernel when using Enduro/X middle-ware.

The benefit for Enduro/X is related with fact that this kernel version offers EPOLLEXCLUSIVE feature. Meaning that highly load balanced server processes won't be waken up for nothing, just to get the notification that some other process have already pulled workload from queue. The EPOLLEXCLUSIVE ensures that only one sleeping process is waken if there are some message arrived on service queue. Even if say 500 load balanced XATMI servers are waiting for message.

The tests was performed here [[https://mvitolin.wordpress.com/2015/12/05/endurox-testing-epollexclusive-flag/]]. This now this feature is available in enterprise grade Operating system. After some 3 years :)
