OK, I confirmed I indeed suffer from hyperthreading.
Booting with ht=off and noht kernel options and running
tglase@tglase:~ $ cat /usr/local/sbin/disable-hyperthreading.sh
#!/bin/mksh
for sibs in $(cat $(find /sys/devices/system/cpu -name thread_siblings_list) |
sort | uniq); do
if [[ $sibs = *,* ]]; then
left=${sibs%,*}
right=${sibs#*,}
echo "Disabling sibling $right for CPU core $left"
echo 0 >/sys/devices/system/node/node0/cpu$right/online
fi
done
… duly disables that, but the ARAnyM speed stays low ☹
