You  could probably  save a  few  microseconds by  omitting the  resource
summary. The significance  to a user is that they  see how much resources
they  have used  up.  Some commands  can  take minutes  of  CPU time  (in
particular database  searches, if large  amounts of data  are retrieved).
The user may not be aware  of it otherwise, attributing the slow response
time to network delays.  It also shows the user what  kind of machine the
server is running on.  If you add //xyz JOB ECHO=NO,  the summary will be
omitted. But  I fail to  see in what way  the resource summary  creates a
problem for the users. They don't have to read it.
