===== TCP =====

=== TCP Listen VI ===

Set the ''resolve remote address'' boolean to FALSE unless you really need this feature. Resolving the name might take a long time if no DNS is available:

===== UDP =====

=== UDP Read ===

Always wire an adequate ''max size'' for the datagram to the UDP Read VI. Ideally, make it a configuration setting. The default size is 548 bytes, which is very often too small and might lead to problems that are very difficult to track down.

> //max size is the maximum number of bytes to read. The default is 548. (Windows) If you wire a value other than 548 to this input, Windows might return an error because the function cannot read fewer bytes than are in a packet.//
