At least by half, and if the antialiasing filters in

converters are designed for it, much better. When using small
period sizes (32 or less), the delay in these filters (which
are usually linear phase) will be the largest contribution to
latency.
This delay is roughy inversely proportional to the transition
band of the filter. If you don't use the full bandwidth that
96 kHz offers (up to 48 kHz) it could be much less than half
the value at 48 kHz. This is why 'digital snakes' connecting
stage and FOH mixer use 96 kHz.
Interesting, I didn't know this. I will re-check my setup with jack_iodelay
and see what values actually turn up.
