Latency will increase with buffer size - the bigger the buffer, the longer it will take to fill, the longer before it can be output. Generally speaking, data is put into a buffer until the buffer is full. When the buffer is full it's passed on to something else for processing or output.

Larger buffers will reduce the number of times that processing has to be interrupted to handle creation of new buffers/buffer output.

Have a look at pages 36/37 of the Advanced Manual for the settings for these.
