Speeding up Web Page Downloading
|
Select Research-Desk Tools > Preferences > Internet Performance
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.
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 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.
