Have you done any tuning on the system? The default values of some of the
SYSGEN parameters are set in such a way to protect less knowledgeable
customers from themselves. At the very least use AUTOGEN with feedback to
see if the report generated indicates a few parameters that could be
downsized. I'm not near a running VMS system right now (restructuring my
home office/computer room and the VMS systems are in pieces down the
corridor) so all of this is coming from memory but something like

     $ _at_SYS$UPDATE:AUTOGEN GETDATA GENPARAMS FEEDBACK

will generate a report file (SYS$SYSTEM:AGEN$PARAMS.REPORT) and not do
anything to the system.
