NAT differens between to-addresses and to-address

Hello,
I am running a IPSec tunnel with a 1st rule for src-nat to-address,
0 ;;; TEST_NAT01
chain=srcnat action=src-nat to-addresses=10.160.200.16/28 src-address=10.230.96.0/24 dst-address=10.208.217.0/24 log=no log-prefix=“test_nat01”

0 ;;; TEST_NAT02
chain=srcnat action=src-nat to-addresses=10.160.200.17 src-address=10.230.96.0/24 dst-address=10.208.217.0/24 log=no log-prefix=“test_nat02”

My question is would it be a performance difference if the natted clients connecting to the remote side with a IP address from the subnet pool 10.160.200.16/28 or is there no difference to the 10.160.200.17 address?

kind regards
Maedo
