Description Several in the networking community are skeptical on using interrupt threads for the network devices. I will argue that not only does it make the solution more simplex, but also increases network throughput. With the introduction of the threaded interrupt infrastructure into 2.6.30, the path has been paved to allow networking devices to take advantage of this. The threaded interrupt may then do all the work needed to hand off the packet to the thread code without all the complexities needed in locking while using the softirqs. I will present my ideas and even a working proof of concept, to convince those that still have doubts that the future of the network and Linux in general, is a kernel free from softirqs.
