Hi, all
IV How to obtain what swi1:net is doing?
IV The short answer is: depending on what your network card is, it could be

IV In your case, you are doing a lot of work in netgraph and dummynet,
IV probably shaping, but have high dummynet usage which probably means its
IV handling the lower level of network IO, probably with a high packet rate.
IV You might try including the following loader.conf tunables:
IV net.isr.direct_force=0
IV net.isr.maxthreads=2
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 SMT threads

cpu1 (AP): APIC ID: 1
cpu2 (AP): APIC ID: 4
cpu3 (AP): APIC ID: 5
ioapic0: Changing APIC ID to 6
ioapic0 Version 2.0 irqs 0-23 on motherboard
netisr_init: forcing maxthreads to 1 and bindthreads to 0 for device polling
# cat /boot/loader.conf
net.isr.maxthreads=2
maxthreads does not affected
#uname -r
9.0-CURRENT
IV ... and report if it helps you. (but be careful: here you must measure
