Software description

As the top seller product of cFos Software, cFosSpeed aims to optimize the user’s Ping time and greatly decrease internet latency or most commonly known as lag. To speed up your internet connection, the app makes use of Traffic Shaping. This method alters the order of internet data packets to prioritize the most necessary traffic and put the less needed in last.


This internet accelerator decides which of your streams must be put first, and thus, all your programs are provided with full bandwidth. This main feature is what causes the significant connection speed up.

Programs which are automatically prioritized by cFosSpeed are the following:

  • Games
  • Multimedia
  • Filesharing (P2P)
  • Voice-over IP or VoIP
  • Other uncategorized programs

This means that the mentioned programs will have improved quality and less lag. This causes the user’s downloads or uploads to not interfere whenever the priority programs are running. Still, the download rate will not considerably slow down as the software features RWIN expansion.

Peer-to-peer filesharing can use your internet connection with unlimited speed. Yet, it will slow down when there is more important internet traffic. Even when under heavy load, the internet response time of the user will normally be fast. Additionally, you will always be able to see the actions of this app through its status window.

Users have the choice to configure the order of the most prevalent network protocols to give the right priority to the programs using them.
