   * **TCPWINDOWSIZE**:​ Specifies the size, in kilobytes, to use for your client node TCP/IP sliding window. The range of values is 0 through 2048. A value of 0 allows the client to use the operating system default TCP window size. Values from 1 to 2048 indicate that the window size is in the range of 1KB to 2MB. If you specify a value less than 1, the TCP window size defaults to 1. If you specify a value greater than 2048, the TCP window size defaults to 2048.    * **TCPWINDOWSIZE**:​ Specifies the size, in kilobytes, to use for your client node TCP/IP sliding window.

Although it uses more memory, a larger buffer can improve communication performance. Specifies the size, in kilobytes, that you want to use for the internal TCP/IP communication buffer. The range of values is 1 through 512; the default is 32. Depending on the operating system communication settings, your system might not accept all values in the range of 1 through 512.
