I see significant difference between number of interrupts on the Intel = and the AMD blades. When performing a test between the Intel and AMD = blades, the Intel blade generates 20,000-35,000 interrupts, while the = AMD blade generates under 1,000 interrupts. There is no longer throttling, but the performance does not improve..=20 I set it via=20 sysctl hw.intr_storm_threshold=3D0 Should this go to /boot/loader.conf instead.
