3091.0. "Process running OA$FORMATTER get high priority and consume much CPU" by HTSC19::ALEXLUI () Fri Jul 30 1993 09:48

    Hi,
    
    Just want to know whether it is normal:
    
    A process (SYMBIONT_00n) running OA$FORMATTER.EXE image will be of base
    priority 7 and chew much CPU time.
    
    Our client system performance has been very poor after upgrading
    ALL-IN-1 to V3.0. Lot of actions have been taken in the VMS level: 
    e,g. memory related system parameter adjusted using AUTOGEN, disk
    reorganisation using BACKUP/RESTORE.
    
    However, for the CPU problem, it has been found almost 100% utilized.
    The above mentioned process is one of the top CPU time chewer. 
    
    Is it a normal situation? Could the priority of the kind of process be
    lowered? To what extent will this affect the ALL-IN-1 system?
    OA$FORMATTER image will consume much CPU time? 
    
    Any idea?
    Thanks
    Alex

	Alex, you might see in some of the topics discussing performance in this conference that the Formatter in ALL-IN-1 V3.0 is from WPS-PLUS V4 and supports proportional spacing. This makes it chew CPU time. I certainly can't recommend running it above user priorities unless you have a CPU to dedicate to running it! Check the queue priority using $ SHOW QUEUE/FULL OA$FORMATTER and it should show the /BASE_PRIORITY which the queue is running at. You should be able to change this using INIT/QUEUE or SET QUEUE specifying /BASE_PRIORITY. I'd suggest a value of 4 since that is the normal interactive priority. BTW, an earlier note also suggested increasing the KOA$HEAP_SIZE value as a way of speeding up the formatter, but watch out for the extra page-faults and working-set you might require. Paul.
