Hi, one machine I'm testing NetBSD on feels sort of sluggish, which is strange because it's got lots of RAM (128GB) and a pair of Xeon(R) CPU E5-2650 CPUs, for a total of 16 physical cores and 32 with hyperthreading. It looks like one of the CPUs is using most of its time doing interrupt processing, "systat vm" often shows ***** in "Intr" and I have a constant buzz of 6.3% System CPU: Proc:r d s Csw Traps SysCal Intr Soft Fault PAGING SWAPPING 1 7 557 281 355 ***** 64 277 in out in out ops 6.3% Sy 0.0% Us 0.0% Ni 0.1% In 93.6% Id pages | | | | | | | | | | | === 2 forks 2 fkppw Checking further: stest: {8} vmstat -i interrupt total rate TLB shootdown 4677209 0 cpu0 timer 1046424629 99 msix2 vec 0 62702425 5 msix6 vec 0 3294854 0 ioapic0 pin 21 84 0 ioapic0 pin 20 21074226 2 ioapic0 pin 17 3344590700017 319462 ioapic0 pin 4 12722 0 Total 3345728886166 319570 stest: {9} grep 'ioapic0 pin 17' /var/run/dmesg.boot pciide0: using ioapic0 pin 17 for native-PCI interrupt stest: {10} pciide0 only has the built-in CD drive, if I see correctly.
