The tcpbuffsize option specifies the size of the internal TCP/IP communication buffer used to transfer data between the client node and server. Although it uses more memory, a larger buffer can improve communication performance.
This option is valid for all clients.
Place this option in the dsm.sys file within a server stanza. You can set this option on the Communication tab, in the Buffer Size field in the Preferences editor.
Place this option in the client options file (dsm.opt). You can set this option on the Communication tab, in the Buffer Size field in the Preferences editor.
Depending on the operating system communication settings, your system might not accept all values in the range of 1 through 512.
-tcpbuffsize=32
This option is valid only on the initial command line. It is not valid in interactive mode.
