Speed Dial is designed to provide maximum acceleration for the Web sites you visit regularly.

So, the more you surf, the faster your favorite pages will load!

Specifically, Speed Dial speeds up the delivery of Web pages four ways:

• Compression. Speed Dial delivers text and graphics more efficiently, using a proprietary compression technology that significantly reduces the size of Web pages and page elements sent to your browser.
  
  
• Caching. Speed Dial improves upon your browser's caching ability. Propel intelligently retains and reuses Web pages and page elements that have previously been sent to your PC. That's why the longer Speed Dial is in use on your PC, the faster your Web pages will load.
  
  
• Persistent Connections. Speed Dial uses proprietary techniques to carefully manage and optimize the communication between your modem and our network of servers through a persistent connection. This eliminates the time wasted re-establishing and closing TCP/IP connections.
• Optional Content Filtering. Speed Dial lets you block unsolicited content, such as pop-up ads and in page ads, which contributes to long wait times.
