Internet Speed Issue

We are using a TZ 400 device. Previously we were having 10 Mbps internet links in which we were getting proper internet speed. Then we have upgraded it to 1 Gbps. After upgradation we are only able to get 90-100 Mbps internet speed through firewall but when we configure the same link on laptop we are able to get proper internet speed.

Then for troubleshooting this I have changed security to performance optimise but still the same issue. I have also checked by changing the MTU value of the WAN interface but still the same issue.

Any Suggestion.
