You need to look at the times:

- How often do you want / need a result?
- How long does the computations take?
- What latency is acceptable?

If you have a sampling rate of 1/T, then the limitig factor
is how much work your CPU can get done in T seconds. You
need to get the job done, shuffle the result away and
be ready to start filling the buffer again by the time
the next sample is available T seconds after the buffer is
full.
