TCP Optimizer is a new and free Cydia tweak that modifies your iDevice’s settings to increase streaming speeds and improve its overall internet connection, including Wi-Fi.

To install TCP Optimizer one your iDevice, you must be jailbroken. Add the repository on Cydia (or any other package manager) and install ‘TCP Optimizer‘. The change will be instantaneous without restart.

The package will:

  • Increase theTCP Receive Buffer from 131072 to 292000,
  • Disable TCP delayed ACK’s
  • Double the number of possible un-ACK packets from 8 to 16 packages
  • Increase the size of un-ACK packets
