Internet, Windows, and Modem Optimized Settings:
ModemSpeedBooster optimizes several internet and
computer settings in order to accomplish the end result of faster
and improved internet experiences. The following is a list of the
major components of Windows Registry settings that ModemSpeedBooster
Maximum Transmission Unit: Is the greatest amount
of data that can be transferred in one physical frame on the network.
If a packet that has a smaller MTU than the packet's frame length
is sent, fragmentation will occur. For Ethernet, 1500 is the maximum
MTU. The unofficial MTU for SLIP servers is 1006.
Maximum Segment Size: Defines the largest segment
of TCP data that the Winsock is prepared to receive. When a connection
is established, the two ends agree to use the smaller of each end's
value. Windows calculates MSS automatically, based on MaxMTU.
DefaultRcvWindow: (TCP Receive Window, or simply
RWIN) Determines how much data the receiving computer is prepared
to get. A too large RWIN will result in greater loss of data if
a packet is lost or damaged. A too small RWIN will be very slow,
as each packet will have to be acknowledged before the next packet
is sent. The RWIN is set to a multiple of the TCP MSS.
Tcp1323Opts: Large window support. Used when an
application requests a Winsock socket to use buffer sizes greater
than 64K. In previous implementations the TCP window size was limited
to 64K, this limit is raised to 2**30 through the use of TCP large
window support as implemented in Winsock 2.
SackOpts: Selective acknowledgements allow TCP
to recover from IP packet loss without resending packets that were
already received by the receiver. Employed with TCP large windows.
MaxDupAcks: Fast Retransmission and Fast Recovery
of TCP connections that are encountering IP packet loss in the network.
Allow a TCP sender to quickly infer a single packet loss by reception
of duplicate acknowledgements for a previously sent and acknowledged
TCP/IP packet. This mechanism is useful when the network is intermittently
congested. The reception of 3 successive duplicate acknowledgements
indicates to the TCP sender that it can resend the last unacknowledged
TCP/IP packet (fast retransmit) and not go into TCP slow start due
to a single packet loss (fast recovery).
DefaultTTL: Specifies the default Time To Live
value set in the header of outgoing IP packets. The TTL determines
the maximum amount of time an IP packet can live in the network
without reaching its destination. It is effectively a limit on the
number of routers an IP packet may pass through before being discarded.
PMTUDiscovery: Determines whether TCP uses a fixed,
default maximum transmission unit (MTU) or attempts to find the
actual MTU. The value of this entry is 0, therefore TCP uses an
MTU of 576 bytes for all connections to computers outside of the
PMTUBlackHoleDetect: When enabled, causes TCP to
try to detect "Black Hole" routers while doing Path MTU
Discovery. Enabling black hole detection increases the maximum number
of retransmissions performed for a given segment.
Memory Optimization Tool: As a bonus tool ModemSpeedBooster
also includes a Ram Optimization tool for smoother PC performance.
By optimizing your computer’s RAM, you can prevent 90% of
system crashes, improve boot time, and make all your applications
ModemSpeedBooster’s Memory Optimizer proactively monitors
your system's level of available RAM to provide the best possible
environment for your PC to run in. Using its advanced RAMFlow system,
it tracks your free memory and automatically manages your RAM to
prevent crashes and boost PC performance. If you are a novice user,
you can just install the Memory Optimizer and enjoy fast automatic
memory management and cache tuning. If you are an advanced user,
you can configure "Target" and "Trigger" levels
of RAM to free up the desired amount of memory. Memory Optimizer
also allows you to view all running applications, even hidden ones,
and how much RAM they use. You can set the CPU priority for these.
