If you google "irqbalance sofirqs" you'll find a lot of stuff about the subject. IRQbalance has its own problems. It's a complex handler and might also affect the performance. There are not too many IRQs active on SOA anyhow. It's not a big deal to figure out a nice share. I get along quite well by focusing at eth0 or usb.
It seems that not having shared interrupts between CPUs is first of all an issue of the kernel parameter CONFIG_HOTPLUG_CPU=y. According to this article "http://www.alexonlinux.com/smp-affinity-and-proper-interrupt-handling-in-linux"; HOTPUG_CPU=y prevents to get APIC properly initialized. Comment: Similar reasons why I also avoid the ondemand govenor. It acts partly very slow changing demands. Other ARCH kernels (my 3.16 on RPI) have introduced the "interactive" govenor some time ago. You'll also find numerous discussions about this stuff on Android forums.
