If you want to see why it may be slow on Windows, then look no further than
Microsoft's own criminal behaviour (as shown by its very own words):
http://boycottnovell.com/wiki/index.php?title=Office_Suites
"Performance/API
* Unpublished Office '96 internal shell extensions (Exhibit PLEX0_5673)
* Office gets a shell optimized for its use (Exhibit PX07377)
* A unique competitive advantage by controlling API, apps and systems
(Exhibit PX00952)
* Undocumenting the shell integration API (Exhibit PX07738)
* Making IShellBrowser internal; "intentionally break those apps" (Exhibit
PX02158)
* Optimize load times for Office (Exhibit PX07949)
* Visio file format policy (Exhibit px03104)
* Excel strawman redacted (Exhibit PX04449) "
