Autocad MAP 3D 2011 slow file saves

Hi Folks,

 

We have a user who is having difficulties with file save times in AutoCAD Map 3D 2011.  She is saving files locally to her C: drive, not across the network.  She has examples of the same file taking 7 minutes to save on one attempt, yet later in the day the same file saves in a matter of seconds.

 

If this were happening on a network drive I could probably account for it, but this is local to her machine.

 

She is using a Lenovo E30 Workstation:

 

Windows 7 64 Bit

Intel Quad Core Xeon E5220

16GB ECC RAM

500GB HDD

NVIDIA Quadro 2000

 

So performance of the system shouldn't be a problem, yet this saving issue keeps cropping up.  She is only running AutoCAD Map 3D 2011 and Vault Basic Client as local apps on her machine.

 

Any thoughts that can be offered would be greatly appreciated.

Hi,

 

try to:

- change sysvar SAVEFIDELITY

- stop your antivirus software (for that test)

- start AutoCAD with option (right click onto desktop icon) ==> "start as administrator"

 

Anything changed?

 

Good luck, - alfred -

Hi Alfred,

Thanks for your assistance here.  We will need to wait for another occurance of it taking a long time to save before we can attempt these steps, as it doesn't happen on all saves, just randomly it will start taking ages to save.

 

With SAVEFIDELITY set to 0 or 1?

 

Cheers

Greg

Hi,

 

>> With SAVEFIDELITY set to 0 or 1?

0 should be the faster option.

Thanks Alfred!

 

Is anything from the drawing lost as a result of setting SAVEFIDELITY to 0 i.e. what does this do to make saving quicker?

 

Cheers

also look at ISAVEPERCENT and ensure it is set to 0.

 

The visual fidelity setting will add additional information into the DWG so earlier versions of CAD (using the same DWG format) can view some of the newer features.  Extra information tends to increase time.  If the user is only working with the single version and does not need to accomadate earlier version, there's no benefit to it.

Hi JGerth,

Thanks for that. This issue is intermittent and does not happen all the time. Do you think that the SAVEFIDELITY would make any difference to an intermittent issue? We have this happen randomly and not necessarily with files of the same size either.

What does ISAVEPERCENT do?


Thanks again for your help.

Cheers

Hi,

Type that while you are in AutoCAD:

 

ISAVEPERCENT<ENTER>

<F1>

 

...and you see what commands/sysvars are doing.

Same for SAVEFIDELITY 😉

Isavepercent is an old setting that stands for Incremental Save Percentage.  Essentially, setting that to anything greater than zero means that changes made to a drawing file are tacked onto the end, and the file increases in size continuously until the 'extra' at the end of the file is a greater percentage of file size than the original file.  at that point, the file is re-written on the next save and only the current information in the dwg is saved.

 

Back in the 1990s, running DOS, with networks rare, slow, and uncommon, and 386 pcs using the then-available local hard drive technology (MFM instead of SATA III) - it was an attempt to speed up saving.    the world of tech has changed in the past couple of decades, and at this point, ISAVEPERCENT should always be set to zero.

Thanks JGerth and Alfred!

 

We've implemented these changes on a different user with the same problem, and it seemed to resolve the issue almost immediately.  Both were required to be set to 0 for this to be effective, but it worked.

 

We will be looking to set this globally for all our users.

 

Now, can I accept more than one post as a solution?
