4.100. 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#817873
- 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.
All users of irqbalance are advised to upgrade to these updated packages, which fix this bug.
