Hi All,
I have a question about the timers on the intel platform.
While looking at the /proc/interrupts on different hosts, I see for an
intel i7 or intel Xeon 5345, the IO-APIC-edge timer is rarely used and
the local timers are widely used but on Core 2 Duo T9500, the APIC timer
is more used than the local timers.
Why there is such difference ? Does anyone have a hint to investigate
why that happens ?
Thanks in advance
