Besides performance testing, could you check how clocksources behave
on this kind of machine?
You can find pg_test_timing tool attached here:

To see which clocksources are available, you can do:
# cat /sys/devices/system/clocksource/clocksource0/available_clocksource
To switch the clocksource, just write the desired clocksource like this:
# echo hpet > /sys/devices/system/clocksource/clocksource0/current_clocksource
