Optimizing Dial-Up Modem Connection Speed
By optimizing the MaxMTU & MaxMSS
settings, together with the RWIN and TTL settings you can increase dialup modem
connection reliability and performance by as much as 200%.
What is the MTU and MSS?
MTU stands
for Maximum Transmission Unit and it
defines the maximum size of a packet that can be transferred in one frame over a
network.
MSS or Maximum
Segment Size defines how much actual data
can put in that packet, and it should be a slightly smaller value than MTU to
allow for packet addressing and other information.
Why do the default values need to be
changed?
By default Windows hardcodes the value of
MTU to equal 1500 bytes. This value is adequate for normal LAN networking, but
when you're connecting to the Internet with a modem this value is too high. This
can show itself in different ways, the most noticeable affect is less than peak
performance.
By adjusting this value to more closely match
the requirements of a modem Internet connection, major performance gains can be
achieved.
Optimizing the
DefaultRcvWindow & DefaultTTL Settings
The optimization of RcvWindow and DefaultTTL, together with the other registry
settings - MaxMTU and MaxMSS can speed up TCP/IP modem networking connections
(eg. Internet connections).
RWIN
(Receive WINdow) is the buffer your machine waits to fill with
data before attending to whatever other TCP transactions are occurring on the
other threads and sockets WinSock has open while a connection is in progress.
TTL
(Time To Live) defines how long a packet can stay active
before being discarded. The default value is '32'
