Recommended nSample for samplingRate=1000

[chipimix]

Hi!
In the definition of the method read(self, nSamples) there is a commend stating:

    Requiring a low number of samples (e.g. ``nSamples = 1``) may be computationally expensive; it is recommended to acquire batches of samples (e.g. ``nSamples = 100``).

I'm using 100 nSamples and everything works like a charm! 👍
However, I'm wondering why can't I fetch all 1000 nSamples at once. Is there an ideal number?
Thanks!
