So I was playing CLR Profiler lately. It comes with a very good document written in word. It is really a simple document with text, and a lot snapshots. The document is about 11M. When I finished reading the document, I noticed my machine kind of slows down a little bit. Hmm, that is odd. So I opened task manager. Word 11 is sitting at 127M VM size.

This sucks. 127M VM size for a 11M document. Not too good.

Then I thought, hmm, maybe I should try other office products.

So I loaded the file in WPS Office 2003 (in case you don't know, WPS Office is a Chinese office suite developed by Kingsoft. It has some features that even Microsoft Office lacks. The particular one I like is big character print. A.k.a, it can print one character in the whole paper. Very handy for posters. Its chinese handling is excellent. The office web site is http://www.wps.com.cn, and you can download a limit trial version from http://www.wps.com.cn/pdown_view.php?styleid=10&id=84). The VM size increased rapidly, and finally stopped at 547M, and the document loaded.

Hmm, OK, compare to WPS Office, Microsoft Office did a very good job.

Next thing I do, I downloaded OpenOffice 1.1, and opened the file in OpenOffice 1.1. Same thing happened. VM size jumped to 541M, and the document loaded.

So I re-opened the document in Word. VM size sit at 27M, as I read through, VM size increased steadily, and stopped at 127M when I went to the last page.

Maybe not a fair comparison for WPS Office and Open Office, but still amazing, what a 11M document can do.
