We have logged Civil 3D defect 1396998 for the slow performance with XREFs, and are actively investigating this. Thank you all for your reports.
We are having similar issues with projects that have a large amount of xrefs. What is Autodesk doing to help resolve this issues?
I have found that going through all the x-refs and doing an Audit on each one can provide a significant improvement, but even then it is noticably slower than working with the same drawings in 2011.
I have a similar issue but I found out what's going on for me and wonder if it's the same issue.
After some serious testing I found that 2012 (at least for me) is having an issue with unreconciled layers. When I open my production drawing that has 3 other xref's I get the same laggy slow down. It reminds me of when I used to remote to the office using dial-up and running Autocad.
Our setup has "layereval" set to 0, so we don't see the unreconciled layers. Open one of your laggy drawings with xref's and set layereval to 1 and then open the layer dialog box and highlight all of the unreconciled layers and RT-click then select "Reconcile Layer", close out of the layer dialog and see if your issue is gone.
It works for me, but I would like to see if anyone else has this before I submit to Autodesk.
Can you give us any updates on this? This is keeping us from moving to 2012.
I thought it was linked to the layer reconciling, but after further testing here it is not. The only things that gets rid of the lag/delay is to remove all the xref's, which is not realistic.
I did test two other tests
1) Disabled Symantec Virus scan (even ended task to make sure)- Did not change issue.
2) Disabled Virus scan, moved all files to my hard drive and disconnected from the network- Did not change issue.
At this time I do not have any updates to post except that we are looking into this defect. I would like to make sure we have your situation covered; would you please send me an email at email@example.com
You too? I have some support requests in about this. I keep getting errors. Once I discovered this I try to audit more than I save. My drawings always have errors. Autodesk tells me they have no problems. I have a big boy computer and the identical files in 2010 were bomb proof and so was our network.
I can tell when someone has been working in an xref file and not done an audit. It will take sometimes 20 minutes to save a file that in 2010 took 1 minute. The save time is killing me. So far I'm not real impressed with 2012. I continues to have the power to leap mountains but can't do it for stumbling over the bumps.
