Estimating the size of the message portion of shared memory

You can estimate the size of the message portion of shared memory in kilobytes.

Estimate the size of the message portion of shared memory, using the following formula:
msegsize = (10,531 * ipcshm_conn + 50,000)/1024
ipcshm_conn
is the number of connections that can be made using the shared-memory interface, as determined by the NETTYPE parameter for the ipcshm protocol.
