Slow AutoCAD when DWG is on a network drive

Whenever I open a drawing from a network drive, AutoCAD will get very slow.
Mostly this takes affect when calling commands opening a dialog box.
Network is WINNT, 100Mps, NTFS File System.
As there are about 1500 files in the directory, I think the problem is that ACAD searches the DCL first in the drawing directory, then in Supportdir.
When I open a drawing in a networkdrive containing only a few files, it works proberly.
Does anyone know a workaround?
(Splitting the directory is not usefull for me)

Hi Grauth

 

I have the same problem.

They mention on their FAQ pages it is a problem
that should be solved by having administrator priviliges.

This is really no solution in a networking
environment.

So I am trying to figure out a solution
myself.

Let me know if you find out something

Hello Niel,

I found a workaround:
I structured by directories for my applicaction, one for Lisp and dcl files, one for DVBs, one for systemblocks.
Than I modified all my programs (lisp and VBA), for example:
In acaddoc.lsp I set the directories:
(setq lspdir "C:\\myapp\\lisp\\")
(setq vbadir "C:\\myapp\\vba\\")
(setq blockdir "C:\\myapp\\blocks\\")
(setvar "USERS1" vbadir) ;to get the vbadir in VBA
Defun a new load for the lisps:
(defun my_load (mylisp /) (load (strcat lspdir mylisp)))

And I replaced each load with my_load.

load_dialog: (load_dialog (strcat lspdir "MyDialog"))

Inserts: (Command "_INSERT" (strcat blkdir "MyBlock") .....

With this modifications my applications are running very fast, althought there are about 1500 files in the current drawings directory.

FYI

AutoCAD 2002 also will resolve shortcut
links that are in the search path folders as well.

This will also slow down AutoCAD.

Hi Niel,

We have the same problem. I've tried the workaround Grauth provided, but to no avail.
I've made some interesting observations (at least on our LAN).

The slow down affects drawings on network drives. The delay is directly proportional to the number of files in the directory. Many files=longer delay in showing dialog boxes and other commands. The delay can be very substantial...its very distracting and unacceptable.

I can prevent the 'slowness' by doing the following:
Start AutoCAD from its icon, but DO NOT open drawings through the File Open dialog. Instead, launch drawings from Windows Explorer. On our network, performance in drawings opened this way is far better. I know this sounds very strange, but please try it and let me know what you see. (repeat: AutoCAD must already be running when you launch the drawings for this effect to be noticed.)
