Very slow opening drawings

We have a NT Network and are running the AutoCad License Manager. Autocad
is installed locally to each workstation. All works well and we have had
this setup for over a year. I am now having problems with some files
loading very slow ( 20 - 30 minutes). When I finally get the file open I
wblock the file and all is well for a day or two before it start to act up.
I notice that when ever I wblock the file, the files size decreases by 20 -
40%.

I have tried keeping the files cleaned by purging but continue having the
same problems. Only when I wblock the file is when the file will open within
a few minutes. This problem has trouble me for a while and cannot seem to
figure out why.

Our network speed is 100 Base and I have ran utilization test. I find that
we are running at 10 - 20% utilization on the network.

Has any one seen this problem before?

Thank You in advance

We also have problems but in a different way.
We are not running the license manager
we have had network consultants monitor our network. It appears that a 3 meg
drawing actually "pulls" 30 meg of data across the network. The consultants
think that it is in the way the NT network is configured. Another thing
about the 3 meg file. it is 700k of a dwg. and the rest is X-Refed in as
overlays. the X-refs are floor plans, HVAC, Plumbing, Cabinetry, ect. plans.
We have not tried to WBlock any drawings so I dont know if that helps our
problem

Jorge,

What is your ISAVEPERCENT setting? (just type ISAVEPERCENT at your AutoCAD
command line). Try zero if it is not set that way to begin with.

ISAVEPERCENT is set to zero.

Be sure not to fall into the often-misguided recommendation to enable XREF
demandloading to "enable with copy". The default AutoCAD setting is
"enabled", however that setting prevents people from opening an XREF while
its being referenced... not good in a network situation. Everyone says to
choose "enabled with copy" instead, and this solves the problem, making
XREFs editable while being referenced. However that solution comes with a
huge penalty, bacause what is does is make full, temporary copies of each
and every XREF in a drawing everytime you call up a drawing with XREFs. You
can control where those temp XREF files go, but in my opinion, it invites a
huige, unnecessary overhead of file transfer and eats up bandwidth.

Instead, set XREF demandloading to "disabled". This setting also makes
XREFs editable while being referenced, but WITHOUT the temporarily
XREF-copying nonsense. In fact, it will set XREF editing just like it was
in R13 with file-locking enabled. The purpose of XREF demandloading has to
do with drawing indexing (INDEXCTL system variable), and its useless to
enable it without exploiting drawing indexing... the two work in tandom..
this fact is often missed. In my experience and testing, drawing indexing
has its own downsides, and for the types of architectural and engineering
drawing we work with, provided no gain, so there is no reason to enable XREF
demandloading.

Keep it simple... set xref demandloading to "disabled"... go to Preferences
dialog, Performance tab, "external reference file demand load".
