Ubuntu routing between two interfaces has very low speed

I'm routing traffic from enp5s4f0 (private) to enp7s4f0 (internet)
this is my interfaces file:
internet interface
auto enp7s4f0
iface enp7s4f0 inet static
address 10.192.129.164
netmask 255.255.255.224
gateway 10.192.129.161
private subnet
auto enp5s4f0
iface enp5s4f0 inet static
address 172.1.1.1
netmask 255.255.255.0
those are the commands which I'm using for iptables:
iptables -t nat -A POSTROUTING -o enp7s4f0 -j MASQUERADE
iptables -A FORWARD -i enp7s4f0 -o enp5s4f0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i enp5s4f0 -o enp7s4f0 -j ACCEPT
I have enabled ip_forwarding successfully and the Nat is successful but it is has very low speed on the servers in private Subnet. Note that the speed is normal at the routing server. Can anyone tell me why the speed is low at this private subnet server please?
This is the speed on the Nat Server:
root@r2s1:~# speedtest
Testing download speed.................................. Download: 89.27 Mbit/s
Testing upload speed............................ Upload: 28.46 Mbit/s
This is the speed on the server behind the Nat:
root@ubuntu:~#
speedtest
Testing download speed........................................ Download: 20.84 Mbit/s
Testing upload speed.................................................. Upload: 1.74 Mbit/s

I don't know if it will make a difference, but because you have static IP addresses you can use SNAT instead of MASQUERADE:iptables -t nat -A POSTROUTING -o enp7s4f0 -j SNAT --to 10.192.129.164. Give us some actual values for "very low speed".

I don't have a way to test with my system, because I am very upload limited due to my adsl modem.
