Calling irqbalance a user space service shows a serious lack of understanding of how irqbalance works. > How can I distribute the interrupt of RX in ixgbevf to all cores? This should already be working over at least 4 cores if this is a dual socket quad core machine, and 8 cores if this is a single socket system with an 8 core CPU with a single shared L3, such as AMD's 8 core Magny Cours. Something obviously broken. irqbalance collects relevant data and builds a new IRQ routing table, which it then makes available to the system chipset to use in lieu of the default table. The new routing table is the "magic" of irqbalance. The running daemon gains little, hence the "--oneshot" option. If it is not working correctly, then I would guess that the system chipset is not being reprogrammed with the new routing table. You should investigate why irqbalance isn't successfully programming the chipset with the new table. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
