CONFIG_HZ_300:
300 Hz is a good compromise choice allowing server
performance
while also showing good interactive
responsiveness even
on SMP and NUMA
systems and exactly
dividing by both PAL and
NTSC frame rates
for video and multimedia work.
proposal for more latency tuning, like:
ivtv
parm: ivtv_pci_latency:Change the PCI latency to 64 if
lower: 0 = No, 1
= Yes, 2 = Max(255)
Default: Yes (int)
or even more:
0 = No = 32
1 = Yes = 64
2 = Hihg = 128
3 = Max = 255/252/248
/etc/modprobe.conf
ivtv ivtv_pci_latency=Max
or
ivtv ivtv_pci_latency=High,Max(150,350)
..something like that
