5772.0. "poor performance" by VARESE::MARINI () Thu Feb 06 1997 11:13

	hello,

	 my customer is having problem using decwindow.
	The system is an alpha 3000.the operating system is
	openvms 6.1 and the motif is the version 1.2-3 with 64 Mb mem.

	He works with  4 windows open.
	In certain circumstances the window refresh ( when he
	click on different windows) takes a couple of minute.
	
	In that situation the cpu is working at 15-20%, the memory
	is 80% used, there is not any i/o activity.

	From a remote connection everythings works well 
	(dir, show sys, edit.....)

	Any help will be very appreciated.
	Thanks a lot.

	Adriano

5772.1	Memory, Parameters, Controller, Quotas	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Thu Feb 06 1997 12:51`	13
	64MB is at the low end of the memory I'd want to use under DECwindows Motif on OpenVMS Alpha -- I'd look at an upgrade to 128MB or more. When was the last time the system was AUTOGEN'd? Which DEC 3000 system, and which graphics controller? What are the UAF settings for the username running under DECwindows Motif? (DECwindows takes considerably larger quotas, and having insufficient quotas can lead to lower performance...) Check the documentation for recommended minimum settings...

5772.3	Here Are Documented Minimums -- More May Be Needed	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Wed Feb 12 1997 15:16`	107
	:> When was the last time the system was AUTOGEN'd? : Just few minutes before the problem. Then chances are there was something missed in MODPARAMS, or there was some other problem... (This is the classic footprint of an AUTOGEN bug, or -- more commonly -- a user that did not include the necessary tuning information in MODPARAMS.DAT.) :> What are the UAF settings for the username running under DECwindows :> Motif? (DECwindows takes considerably larger quotas, and having :> insufficient quotas can lead to lower performance...) Check the :> documentation for recommended minimum settings... : The system is an alpha station 200 4/100 instead of dec 3000 The slowest Alpha ever shipped...
