CYDIA (TWEAK)

Speed Up YouTube Streaming On iPhone, iPad, iPod touch

In order to install this tweak, you need to add the http://cydia.pushfix.info/ repository to Cydia, or any other compatible package manager. After refreshing your sources, you should see “TCP Optimizer” on the package listings. The tweak should take effect right away, without a restart,  and enable you to watch YouTube videos at decent speeds.



TCP optimizer modifies a few settings inside iOS, including increasing the TCP receive buffer from 131072 to 292000, disabling TCP delayed ACK’s, allowing a maximum of 16 un-ACK’d packets instead of 8 and set the default package size to 1460 instead of 512. These changes won’t only speed up your YouTube videos, they’ll also improve your internet connection’s performance overall, including Wi-Fi network connectivity.
