Network Bottlenecks - GFXRebels

grachel21 · 12-06-2007, 02:05 AM

Our IT dept. switched out the switches in the data closet. After the switches were changed, there was a drastic slowdown in the AutoCAD performance due to the network lag times. We run around 25 seats of (standalone) AutoCAD 2004/2006 working on files that sit on a novell cluster server.

Any solution to enhance the performance of the AutoCAD files across the WAN?

Your suggestions will be greatly appreciated.

Cheers,
Rachel

Sometimes when I'm working on really large files, like Photoshop files, I will copy the job folder to my local drive to work on the project and then save it all back to the server when I'm done.

Hi,

Our switch engineer says the only change he made was that, that he eliminated
broadcasting and/or multicasting over the network.

Anyone knows whether AutoCAD requires this, to run efficiently, on a large corporate network or not?

The intermittent, random lag times while using AutoCAD are quite frustrating to the CAD users here.

Thanks

Right-click your AutoCAD icon and choose Enable/Disable Digital Signature Icons.

Uncheck the box. Click OK.

Try this. It might solve your issues.

Thanks for the advice.

I tried both unchecking the Digital Signature Icons and the new registry keys but neither seem to have helped. The system still lags every 10-20 minutes. I have tried these on some of the other machines but it has not seemed to help them either.

The network lag seems to be only affecting the systems that have AutoCAD installed on them.

Any help.......

We had faced some similar sort of issues. It stimulated while accessing certain AutoCAD files being located on our main server. Whenever a request was sent to access any of the files from the server, it would cause a lapse as the PC was looking back at the main server. Our IT guys have managed to solve the problem, but how, I dont know. I will try to find out and let you know about that.

We are eager to know about the solution that your IT guys used to solve this issue.

Thanks,

Our IT guys have deployed the appliance from Riverbed. They have deployed Steelhead appliances and look much happier with the performance they are experiencing with it. You can try and test the same and can go through one of their performance briefs at the following link:
