Improving performance for stsadm -o export and import

  • Article

Last week we've migrated content from one farm to another using stsadm –o export / import. The export of the 2GB Content DB took around 2 hours. The import of that content into the new farm took around 5 hours. During that import process we found a nice option for speeding up the import process. After executing:

Netsh int ip set chimney DISABLED

The import process was really speeding up. It seems that some servers are having issues with this TCP Offloading functionality. You can find additional information about this topic here:
