i the patch in fact enables this too: you can more agressively get irqs and softirqs executed by increasing max_rate just above the 'critical' rate you can measure. (and the blocked-interrupts period of time will be enough to let the softirq work to be finished.) So in fact you might even end up having higher performance by blocking interrupts in a certain portion of a timer tick - backlogged work will be processed. Via max_rate you can partition the percentage of CPU time dedicated to softirq and process work. (which in your case would be softirq-only work - which should not be underestimated either.)
