Actually, I've never understood how it is possible to have anything
else BUT 2 buffer notifications
With relatively large (dozens of ms) buffers, there is no reason to
have packet size (and number of notifications) more than 2, because
a time equal to a half of buffer duration is enough to react and
But with small (units of ms) buffers, the time is not enough. For
example, with 10 ms buffer, you have only 5 ms to get the CPU, while
internal kernel delays may be long (see LatencyMon measurements).
Using at least four parts/packets, you might have 7.5 ms, which is more
