We had high CPU utilization peaks in the past, which lead to some audio issues (clipping). We were using debian at that time, which was a customer-side requirement.
I'm not a kernel guru but I remember this had something to do with kernel timer cycles and the issue was address by adding "divider=10" or "divider=100" as a kernel's boot loader option.
Interesting. This kernel option is designed to reduce the valy of CONFIG_HZ at run=time, so if you have a 1000Hz kernel, setting divider=10 at boot time will effectively give you a 100Hz kernel. This seems to fly in the face of other recommendations on this kernel setting! Debian default kernel sets CONFIG_HZ=100 CentOS default kernel sets CONFIG_HZ=1000 Regards,
