#Page Swapping
6 messages in this thread
Can anyone out there help me with the optimum Setup Configuration for my
PC that is running ACAD 11c2…I have an Everex 486/33, 16 meg Ram, 1.2 Gig
HD and running under MSDOS 5.0.
My main problem is Excessive Page Swapping….I'm lost when it comes to
fine tuning AutoCad for Performance. I have a 1.3 meg Schematic drawing
and when I perform a status command at the beginning of the session I get:
Virtual memory allocated to Program 9248K
Amt of program memory/Total virtual program size: 99%
Total Conventional memory: 428K Total Extended Memory: 15360K
Swap file size: 25788K bytes
Page faults: 0 Swap Writes: 0 Swap reclaims: 0
Now this drawing file is very Text intensive, it contains all ROMANT fonts
within each BLock (that contains at least 29 attributes). I need the
ROMANT fonts for clarity as this drawing is used for publication. I tried
changing to a standard font but upper management really doesn't care for
them, as far as readability goes. Does anyone know of a third party font
developer that has fonts that compare to ROMANT but with less of a byte
count per character, that would help a great deal.
Sorry to get off track, but after about a half hour of editing this
drawing, I do another STATUS command and get:
22420K, 65%, 432K, 15360K, 97656K, 26935, 11023 and 9791
respectively. All snaps are off, the hard disk has been optimized, and the
STATUS info has me baffled. Can someone send a sample Config.sys &
Autoexec.bat file that might help me out. My hard drive sounds like it
want to take a walk out of my machine…Any help would be most
appreciated.. —Tom—
Tom – You've got a 25+ megabyte swap file there, buddy! I don't know if its
the font, or not, but if you can make some of the attributes hidden, or use
ROMANS for editing, and ROMANT for plotting, that might help. Essentially,
you've got a drawing that's probably generating a huge amount of display
vectors, and AutoCAD has to keep track of each one of them. Usually, I
advocate using a font that comes in two versions – one used for display and
editing, and the other for plotting. Just swap out .SHX files when you're
going to plot the drawing.

Tony,
How've ya been, did you get that 486/50 yet, I just ordered a Compaq
486/50 for use in UPS, I will have to just suffer with this 486/33 here.
Tony, I'm lost when it comes to figuring out what all that page swapping
tripe means when I do a Status command. I believe I have enough Hardware,
if 16 meg of RAM and 1.2 Gig of HD isn't enough, I don't know what is. I
have all of my extended memory dedicated to ACAD and stripped the config
and autoexec to bare bones. I'm using MSDOS 5.0 with HiMEM and have a good
amount of base memory. I even set aside 40 meg for page swapping to the D:
drive, I have (2) 500 meg partitions. Am I killing myself with a huge page
swapping area? I thought the more the better. I've upgraded the PharLap
with the c2 upgrade. I understand what you mean by using a different font
for editing and another for plotting. But this drawing is now (21) 8.5" x
11" set side by side and we usually PRplot each page as we edit each.
There is a known BUG in R11 that changes the text justification is some
block attributes when you use DDATTE. ADESK confirmed the bug on this
forum to me but who knows what they plan on doing to fix it. My blocks
have at least 31 attributes each and it's a royal pain in the butt to see
the text go from centered or left justification. The only work around – is
to completely DELETE the text in the dialogue box, hit enter, repick the
block and reinsert the text again, and the justification comes back. Other
than that, things are the same – work and more work…By the way, I'm going
down for the 3rd time, getting married on Apr 11 and going to Cancun for a
week…hope to hear from you before then…..Tom [UPS]
Tom:
Make up a plot directory and put your original .shx files in it. Copy a
romans (which I >think< is the simplest roman font) to your acad directory
using the file name romant.shx. When you want to plot, replace the
romant.shx file in the ACAD directory with the 'real' romant file.
Don't use a different font because the spacing may be different. Also,
check out the QTEXT variable.

Tom – Zowie. A 1.3 Mb drawing file that expands to 25Mb upon start up,
and produces a 97Mb swap file after half an hour of work? My goodness,
that's a lot of text. The 29 attributes per block are the main source of
the overhead, I'm sure. You might try freezing some of the layers that
aren't in use. Now you know the value of extended entity data, eh?
As some of the fellows have suggested, you can use different font files for
work and for plots. Use the STYLE command to replace ROMANT with TXT while
you're working, then redefine the styles for the attributes to ROMANT
before you plot.
