Using Internet Performance Settings
|
|
Research-Desk Professional speeds up web browsing because it uses more connections.
(Research-Desk uses up to 10 connections per server versus the normal and HTTP/1.1
compliant 2). It also optimizes your TCP/IP settings to speed up web browsing.
To change these settings, select Research-Desk Tools, Preferences, Internet Performance.
Step 1:
For maximum speed, move the HTTP Connections Per Server slider over to the far right.
Step 2:
Then select the TCP/IP Setting that best corresponds to your connection type.
Choose Optimize for Dial-Up (56K) Connection if your Internet connection is via
a dial-up modem of up to 56Kbps. Or choose Optimize for Broadband (>128K) Connection if
your Internet connection is a high-speed connection such as ISDN, DSL, Cable, T1 or a corporate LAN.

How Research-Desk's TCP/IP settings Work
|
Research-Desk changes the TCP Window Size and Selective Acknowledgement settings to optimize TCP
parameters in accordance with recommendations from request-for-comments (RFCs) released by the
Internet Engineering Task Force (IETF).
The TCP Window controls how much data can be downloaded before your computer must send an 'acknowledgement'
- a small piece of information acknowledging receipt of the data. Larger windows yield better performance
because less time is spent sending acknowledgements. Smaller windows yield better error recovery because
the more frequent acknowledgements help identify erroneous transmissions more quickly. Each error
requires retransmission of the whole TCP window.
The TCP Window Size affects transmission speeds and quality even more with asymmetric connections such
as Cable, ADSL and 56K modems because asymmetric connections deliver significantly different upload
and download speeds.
Selective Acknowledgements (SACK) lets your computer request retransmission of only the lost packets,
instead of the whole TCP window. This provides potentially huge performance advantages, especially
with a large TCP Window as only the lost bytes instead of the whole TCP Window (which may be hundreds
of kilobytes) is retransmitted
Research-Desk enables SACK and selects an optimal TCP Window Size based on the type of connection.
These two settings can significantly speed up web page viewing.
