[comp.sys.next] Sluggishness when altering a large IMPROV worksheet

Robin Bush (05/14/91)

I have an Improv worksheet containing 3 categories, 50 groups and 10 equations.  
I find that once the equations are in place, making any subsequent structural  
changes to the worksheet can take a half hour or longer! Similarly, adding or  
editing an equation takes forever.  I have already set recalculate to manual.  
Can anyone tell why this is happening, and how I can speed things up? 

Thanks

Pretty polite of you to call it "sluggish" if it takes half an hour.

First of all, I have no idea why, but I'm not above speculating :-)

Is it possible that you have lots of processes running and you are short
on memory and the operating system is just thrashing terribly?  Is
your disk almost full?  Does the disk make a lot of noise during this
half hour?  Is anybody printing to a printer hooked up to your machine?
Um, let's see, what else.  Maybe your document just triggers one of those
"worst case scenarios" that we applications developers hate so much :-)

One thing you (Robin) might want to do is open a terminal window and do a 
      ps -axv
to see what processes are using up memory on your machine.

With this large worksheet in place, is it just Improv that is sluggish, or are  
all applications sluggish?

Thanks to both you and everyone else who has responded to my plea.  
I have a 040 machine with 32 Meg, little else running besides Improv, 
nobody printing, everything else runs ok,  etc, etc. The NeXt is not chugging,  
it just sits there quietly while the Improv wheel turns and turns.  I called  
the Improv support line, they said they have been getting lots of calls from  
people with similar problems  (trying to make structural changes to a big data  
set having  lots of structure and equations).  They said they were surprised  
that people were using Improv for so many different things, and that their  
engineers had only made sure that it worked well for worksheets like those  
little business ones they show in the documentation!!! They also made what  
turned out to be a useless suggestion: to save as an .imx file instead of an  
imp file, the logic being that dumping the formatting might help.  Turns out  
that all you get in an .imx file is a picture of your equations - they don't  
work.  


Anyway, thanks for the suggestions.
