SHORT attribute

The Virtual Channel Router (VCR) system task keeps a small buffer at the receiving end of each virtual connection. Short messages that fit entirely within this buffer are handled more efficiently than longer messages. If you do not specify otherwise, each buffer is 64 octets long. This default setting may be overridden as follows:

connect ? task1[0] task2[1] short=128

This connection uses a 128-octet buffer. SHORT=0 is allowed, and forces all messages sent over the connection to use the slower long-message mechanism. The value given for SHORT must be less than the maximum UPR packet size.

The SHORT attribute makes sense only for virtual connections: it is ignored for physical ones.
