1. Configure a remote TCP / IP connection through the registry in Windows XP.
To configure, run RegEdit (Start -> Run -> regedit).
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters
String parameter DefaultTTL (TTL - Time To Live) - the lifetime of the package . TTL can take values ​​of 32, 64, 128. It is provided so that when searching for the destination of a packet, the routers do not get hung up. As soon as the value of this parameter exceeds the allowable value, the packet is considered to be in a cycle and is destroyed. Recommended value (64).
The string parameter TcpWindowSize (RWIN - Receive Window) is the sending window. The RWIN value is calculated using the formula DefaultMSS * n, where n is 4, 6, 8 (1460 * 8 = 11680). When you send a request to the server, it has the right to send you RWIN the number of bytes, without waiting for confirmation of a successful reception. If RWIN is equal to DefaultMSS, the server will wait for confirmation after each packet is sent. If you specify DefaultMSS * 20, the server will immediately send 20 packets, which will increase their loss. Recommended value (5840)
The PMTUDiscovery (Maximum Transmission Unit) string parameter is the maximum transmitted packet. The possible values ​​for MaxMTU are 552, 576, 1002, 1500. By default, in Win XP, the value (1) is automatic. The higher the value, the larger the packet and more data you will get. With the maximum value, the modem will send more data, but with bad communication, packets are lost and it takes longer to resend large packets. Another problem - the standard for routers for a long time was the value of MaxMTU = 576. Now everywhere in different ways. The recommended value of MaxMTU (1) is automatic.
The string parameter DeadGWDetectDefault is the location of black holes. If this parameter is set to (1), then before starting the connection, the dead routers will be checked on the way to the server. This parameter strongly slows down the protocol due to unnecessary search costs. Recommended value (0).
Double parameters are located in the section:
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ MSTCP
The string parameter TcpWindowSize, PMTUDiscovery is recommended to be set by parameters of the provider's server. If you do not know the recommended values.

Conclusion:


These settings can increase the speed from 10 to 40%. These settings are individual for each one depending on the quality of your connection.
For automatic tuning, you can use the special program TweakMASTER Pro . Other programs I do not recommend. Checked.

3. The advice of closing Flash-BIOS to write can be harmful. The fact is that BIOS can be solved most often (at least hot on the specialists in almost any normal computer office), but to restore the information on the hard drive, which mixes into the porridge Win95.CIH and its clones, provided that he It was not possible to reset the bivis to a much more difficult, and most often it is simply impossible.
