[mod.computers.vax] VMS HELP speed

lf@VAX1.CCS.CORNELL.EDU (Larry Fresinski) (07/02/86)

I've noticed that HELP SET option can get very very slow in VMS 4.x. It's
particularly bad if one enters an incorrect subcommands. Commands other than
set are slow too, but SET is a popular command. Is there a solution to this
problem? -LF-

Have you decompressed the main help library?  If not, try it.  By the way, on
the (at this hour) lightly loaded 780 I'm on, the HELP command is heavily CPU
bound, taking 8.5 CPU seconds to complete its response to the command: 
	$ HELP/NOPROMPT/NOINSTRUCT/OUTPUT=NL: SET FUBAR
so with 7 computable processes, that would mean a minute or more in real time.
Making the library contiguous causes a barely measurable improvement.
