You as well have the choice to type a custom MTU value. Normally, MTU can in safety be set at 1500, however a few types of connections, and a few routers use lesser values. It is just essential to edit the MTU value in such particular cases. For instance, the utmost MTU worth for Windows XP PPoE encapsulation is 1480. I set the MTU to 1480 in SG TCP optimizer best settings but the SpeedGuide.net TCP Analyzer Results show it at MTU: 1448 why is it diverse?

If you have a router, log into your router setup and make sure MTU is place to 1492 and restart your router to take result. Afterward, endeavor the below among TCP Optimizer:

• General Settings tab:

1. Custom settings: check
2. Modify All Network Adapters: check
3. Network adapter selection: NIC
4. MTU 1492
5. TCP Receive Window: 127776
6. Max Duplicate ACKs : 2
7. TCP 1323 Options:
8. Windows Scaling: checked
9. Timestamps: uncheck

• Advanced Settings tab:

1. Max Connections per Server: 1
2. Max Connections per 1.0 Server: 10
3. Local Priority: 1
4. Host Priority: 1
5. DNS Priority: 1
6. Netbt Priority: 1
7. QoS: NonBestEffortLimit: 0
8. ToS: DefaultTOSValue: 80
9. NegativeSOACache Time: 0

After that choose Apply Changes and restart to take consequence
