So far this seems to work surprisingly well - even for users who use editors other than Emacs (yes, we need to try harder...). We have created a web service so users can upload an org-file and get a preview of the generated HTML page.

You are using option -Q with emacs command. That itself should give you
the maximum performance. 

I don't think that you will get any performace improvement if you use
