If the subsystem(s) aren't running, about the only overhead would be for the space for the SSCT entries (around 20 bytes, plus a slight amount of CPU time to execute any INIT routines defined for the subsystems, but when weighing this against the management/change control issue, make it, in my opinion, a no-brainer to share one IEFSSNxx across the plex.

For example.. if I have 1)10 subsys (same on all systems), 2)10 production (db2, mq etc) 3)20 test subsystems (more db2 and mq) What is the impact of having a single IEFSSN00 that contains all of the subsystems v.s. separating it out somewhat?
