It has been mentioned on civil3d.com, AECnews.com and SearchStorage how the file 2007 DWG file format used in AutoCAD 2007, AutoCAD 2008 and now also AutoCAD 2009 might affect users of WAN acceleration appliances like Riverbed’s Steelhead appliances. The performance has been a real problem.
Autodesk now has added a Knowledge Base document on this issue: Potential for reduced write performance for Riverbed WAN links when working with AutoCAD 2007 DWG files
Users of Riverbed or other affected WAN acceleration solutions can implement the following immediate workarounds that improve write productivity.
- Using a feature in AutoCAD called “Incremental Save Percentage” (ISP), and setting it to 50
- Using a version of the DWG format other than the AutoCAD 2007 DWG format
Notice that there are some commands that does not respect this setting to save in another version. Using Saveall and the drawings will be saved in 2007 format.
