IRQ Pinning Enabled by Default on LoadMaster VNF Builds

When using LoadMaster firmware version 7.2.53 (and Long Term Support (LTS) version or a subsequent release as a Virtual Network Function (VNF) node in a LoadMaster Multi-Tenant (MT) deployment, the IRQ Pinning option on LoadMaster is now enabled by default when the VNF is deployed to improve overall system performance.

You can access this option by going to System Configuration > Logging Options > System Log Files > Debug Options.

Only change this option in consultation with Kemp Technical Support.

When you change the IRQ pinning option from off to on, IRQ pinning is enabled on all network interfaces that are assigned an IP address. When IRQ pinning is enabled and you add an IP address to an unconfigured interface, that interface will not have IRQ pinning enabled until you either toggle the IRQ pinning off and back on again, or the system is rebooted.
