Firstly, your file is 18MB in size (not 5-10 as your OP) ... but hey, it opened on my Vanilla 2008 in a matter of 1min. No worries there. However, I've got a lisp running on each DWG opened to remove XRef Annotation Scales. It listed the following:
And then I did the usual, purge, -purge regapps:
44848 XREF scales deleted.
Audit also listed
18 registered applications deleted.
The file's now down to 3.8MB and opens in les than 10 sec - attached.
Total errors found 99 fixed 99
So it should have run slower than yours (methinks). Maybe there's something wrong with your installation, something like a folder unfound in your support paths (that usually slows things down).

- Intel Core2 6600 @ 2.4GHz
- 2.00GB RAM
- nVidia Quadro FX550
The main problem I can see was those XRef scales. Search this forum as well as the AutoCAD General forum for the words scalelist nighmares. There are a few utilities available to fix these.
