5.116. irqbalance
Updated irqbalance packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The irqbalance package provides a daemon that evenly distributes interrupt request (IRQ) load across multiple CPUs for enhanced performance.
Bug Fix
- BZ#845374
- The irqbalance daemon assigns each interrupt source in the system to a "class", which represents the type of the device (for example Networking, Storage or Media). Previously, irqbalance had some problems while classifying certain NIC devices that resulted into performance impact on affected systems. With this update, the NIC classification mechanism has been updated to work with all types of NICs.
All users of irqbalance are advised to upgrade to these updated packages, which fix this bug.

Bug Fix
- BZ#682211
- The irqbalance daemon assigns each interrupt source in the system to a "class", which represents the type of the device (for example Networking, Storage or Media). Previously, irqbalance used the IRQ handler names from the /proc/interrupts file to decide the source class, which caused irqbalance to not recognize network interrupts correctly. As a consequence, systems using biosdevname NIC naming did not have their hardware interrupts distributed and pinned as expected. With this update, the device classification mechanism has been improved, and so ensures a better interrupts distribution.
