If you "hide" the xrefs (by renaming or moving them) - does the base file open OK w/o them?

If so, add the xrefs back in one by one (so AutoCAD can find them) and troubleshoot that way.

When it slows down again, you will have found the misbehaving xref.

 

If it's still slow w/o the xrefs loading, then zip up the DWG and post if you have exhausted all other options on your own.

Usual suspects.  Proper object enablers installed for the proper third-party version on the proper AutoCAD version, annotation scales, DWG save versions.  Isolate, audit, and clean everthing separately then re-XREF them.

Great suggestions from the previous posts. In addition try the following:

Check Origin

Turn on all layers and draw a line from 0,0,0 to the objects. 

Now use “Zoom Extents” to see if the objects are close to the origin or only visible very small.
Also switch to Front or Back view to look after Z-values.

If the objects are far from origin move them to 0,0,0.
Save the file including all changes with a new name.

Perform Recoverall
Open the drawing in AutoCAD 2012 and enter Recoverall in the command line.
The drawing file and all attached xrefs will be recovered and saved in the current drawing file format.
Copies of the original drawing files are saved with the BAK extension.
Custom objects are all updated if the corresponding object enablers are present.

I just came accross this thread by chance.  I think the original posters point is more, why does it open ok in 2007, and so slow with 2012 with a much higher spec machine.  I would be interested in a constructive answer to this.  As I sometimes have a similar issue.  Have found that the newer versions of Acad and faster machines, the time to open drawings is slowing down with xrefs.  It seems to be going backwards.  All the solutions posted dont really deal with the main issue that the OP is asking about.

One trick that has worked for me is to set your Anti-Virus software to ignore autodesk related extension files (i.e. DWG, LSP, DCL, DWT, etc)

Perception can be a big issue.  Users spend several years working on a specific version of AutoCAD, making tweaks to their work processes, changing settings, etc.  Then they move to a newer version and promptly forget all the cumulative changes they made to optimize the last version and ignore the new settings that are available, or persist in using old settings which may not work as well (calling regsvr in order to use ObjectDBX with LISP, for example).  Not many are capable of the grinding, brutally logical process of change/observe/document to identify *exactly* what they do and what the result is.

 

And sometimes the program *is* in fact slower.  Hardware may have moved quickly but not as quickly as the software has grown.  Plus there are more demands on system resources than ever before (did anyone even consider streaming hockey games alongside AutoCAD 2007?).
