I am going to test with hpet when i get the chance

Here are some numbers that make the mystery
Folks,
I have posted this before but got no good response and i havent had time
to chase it.
While doing some batching tests with pktgen and then with a simple
client server app with udp, it does appear that the clock source used

can you make sure hpet is enabled as well?

acpi_pm: 108, 110, 111, 91, 108
tsc: 143, 108, 161, 129, 108
jiffies: 132, 138, 132, 146, 150
