How Fast is It?

• STI's Advanced Image Compression delivers faster acceleration.
• Clearer and crisper graphics so you'll see even sharper images of the faster-delivered graphic.
• Enhanced text compression provides smaller, faster, "lossless" compression of text and delivers additional acceleration.
  
  
  What is lossless?
  lossless = reconstructed exactly from the compressed data; the same as the original.

With the STI Accelerator, web pages load up to five times faster. The more often you visit specific websites, the better the performance you will receive.

Here are some tests run with and without the STI Accelerator:

Popular Web Sites	Without Accelerator*	With Accelerator*	How much faster with Accelerator?
Ebay	11.65 seconds	2.97 seconds	3.92 X faster!
USA Today	32.43 seconds	3.77 seconds	8.60 X faster!
Mapquest.com	30.56 seconds	5.01 seconds	6.10 X faster!
Monster.com	11.74 seconds	3.04 seconds	3.86 X faster!
CNN	11.68 seconds	2.26 seconds	5.17 X faster!

Most Web content will be accelerated, but there are certain exceptions:

What will be accelerated	What stays the same
All text - HTML, markup, and javascript	Secure pages, such as those used for online banking and credit card forms and pages accessed over VPN. Secure pages are not accelerated because that would necessitate a breach in the HTTPS protocol, potentially allowing the logging and clear text visibility of the user's private data such as credit card numbers, PIN codes and bank access information. This level of security risk would be unacceptable to us and to our subscribers.
Most graphics & photos - including jpeg and gif images	Streaming media, and audio and video files are not compressed because video files and audio files delivered in the streaming format have already been compressed to the furthest extent possible. To attempt additional compression would degrade the streaming media past an acceptable level.
Most banner ads - including animated gif images and Macromedia Flash content	Files downloaded outside your browser using FTP are not compressed
All browser-based emails
POP3 and IMAP protocol emails and attachments
Outgoing SMTP email - especially acceleration of large messages with pictures or attachments including Microsoft Word, Excel, and PowerPoint files
MP3 files, executables & other files — when downloaded from within your Web browser (depending on the quality of your connection).

The STI Accelerator is designed to provide maximum acceleration for all websites and additional acceleration for the websites you visit regularly. So the more you surf, the faster your favorite pages will load!

Specifically, the STI Accelerator speeds up the delivery of web pages five ways:

• Compression
  Images and other graphic objects are compressed by removing some of the image detail. This results in dramatically smaller images that are delivered to your computer much quicker. You may set your own default level of graphic compression through the STI Accelerator Menu. You may also right-click on any image or web page and select the menu item to refresh the image or web page in full quality.
• Caching
  The STI Accelerator intelligently retains and reuses web pages and page elements that have previously been sent to your desktop.
• Persistent Connections
  The STI Accelerator optimizes the communication between your modem and our network of servers. This eliminates the time wasted re-establishing and closing TCP/IP connections.
• Chunk Encoding with Parallel Connections
  When a user begins to download a file larger than 100KB, this feature downloads different segments of the same file from different locations.
• Optional Content Filtering
  The STI Accelerator lets you block unsolicited content such as pop-up ads and in-page ads. Blocking these ads causes web pages to load faster.
  
  
  • Pop-up Windows
    (Windows Only). The STI Accelerator can block pop-up and pop-under windows that clutter your screen and slow down your surfing.
  • In-page Ads
    The STI Accelerator can block most advertisements that appear on web pages. When an ad is blocked, it is replaced with a light gray box on the web page to make sure that web pages maintain their intended design. You can easily view blocked ads by right-clicking on the gray box. As with pop-up blocking, you can turn this feature on and off any time you like.
