Hi VanBuren: Just a question why are the DefaultReceiveWindow & the
GlobalMaxTcpWindowSize different? also above you said DefaultReceiveWindow should be a multiple of 1024 .Speed guide Tcp/analyzer uses mss specially 1460 as the multiplier. Which is correct? Cholla
hey Cholla

The win2k and XP Tcp Settings is diffrent from windows 98
this is a quote from
http://www.dslnuts.com/2kxp.shtml1. DefaultReceiveWindow - The number of receive bytes that AFD buffers on a connection before imposing flow control. For some applications, a larger value here gives slightly better performance at the expense of increased resource utilization.
Value Type: REG_DWORD
Default: 4096/8192/8192
2. DefaultSendWindow - This is similar to DefaultReceiveWindow, but for the send side of connections.
Value Type: REG_DWORD
Default: 4096/8192/8192
17. GlobalMaxTcpWindowSize - The TcpWindowSize parameter can be used to set the receive window on a per-interface basis. This parameter can be used to set a global limit for the TCP window size on a system-wide basis.
Value Type: REG_DWORD—Number of bytes
Valid Range: 0–0x3FFFFFFF
Default: This parameter does not exist by default.
32. TcpWindowSize - This parameter determines the maximum TCP receive window size offered by the system. The receive window specifies the number of bytes a sender may transmit without receiving an acknowledgment. In general, larger receive windows will improve performance over high (delay * bandwidth ) networks. For highest efficiency, the receive window should be an even multiple of the TCP Maximum Segment Size (MSS).
Value Type: REG_DWORD—number of bytes
Valid Range: 0–0x3FFFFFFF
