Adaptive Server reserves enough space for all configured user connections to log in at the default packet size. Large network packets cannot use that space. Connections that use the default network packet size always have three buffers reserved for the connection.
Connections that request large packet sizes acquire the space for their network I/O buffers from the additional network memory region. If there is not enough space in this region to allocate three buffers at the large packet size, connections use the default packet size instead.
