Hi, I have a rather slow Intel Atom CPU, so when running NFS copy over 1GbE, one CPU is quite busy servicing interrupts. So with NetBSD-8 there is intrctl command:
# intrctl list interrupt id CPU0 CPU1 CPU2 CPU3 device name(s) ioapic0 pin 9 0* 0 0 0 acpi SCI ioapic0 pin 1 0* 0 0 0 pckbc1 kbd ioapic0 pin 12 0* 0 0 0 pckbc2 aux ioapic0 pin 16 0* 0 0 0 i915, uhci3 msi0 vec 0 0* 0 0 0 hdaudio0 ioapic0 pin 18 1538867* 0 0 0 unknown, uhci2 ioapic0 pin 23 50* 0 0 0 uhci0, ehci0 ioapic0 pin 19 0* 0 0 0 uhci1, ichsmb0 ioapic0 pin 14 276896* 0 0 0 piixide0 primary ioapic0 pin 15 0* 0 0 0 piixide0 secondary but trying to use it: # intrctl affinity -c 1 -i 18 intrctl: sysctl kern.intr.affinity: No such file or directory Any idea? Also is it possible to assign a single interrupt ID to multiple CPUs, i.e. load balance it? Another issue I'm seeing is that NFS quite quickly grinds to a halt, but I've seen this before. Doing "ls" on the local NetBSD file system where NFS server is writing, also hangs for some seconds, but eventually returns.
