I recently saw a suggestion for running cat /proc/interrupts, or something like that to check on the timing of updates.
watch -n1 cat /proc/interrupts and check that you roughly get 250 interrupt 0s each second (or 1000 on 9.3). But it doesn't sound like this is your problem.
Periodically I do see many lost ticks with dmesg - hence starting this
You mean you see some of them each hour where you see the slowdown? Check it for a few hours and compare the time stamps in the log.
thread ;) I confess to knowing absolutely nothing about timing in Linux, so can't comment on whether these kernel parameters should affect the time reported by the OS, but it seems logical to me....?
You can test if notsc helps, but it's only a small chance imho. -Andi
