After my own use, it indeed speeds up the process of opening web pages while downloading using eDonkey. Of course, it doesn't just have this one function for ISDN and DSL connections. After testing, it is very effective for improving the speed of ADSL dial-up, routers, PPPoE FTTB, and has received a lot of positive reviews online; you can Google it yourselves.
After installation, no further settings are needed as the software itself is already optimized to its best setting state. Be sure to enter the registration code as prompted.
Remember: Do not use the last word in the registration code text.

The software's interface skin is very beautiful, dynamic, and supports a skin-changing function.
