One other gotcha with Bonjour syncing:

the Mac has to be running OmniFocus at the time you want to sync


I think the original poster is a new OmniFocus user, however, and perhaps isn't suffering from an accumulation of old data. Might be suffering from an accumulation of new embedded attachments, however! Are you attaching documents or emails to your actions? Enough of that coupled with a slow iPhone data connection could lead to long sync times as well. On the settings page in the iPhone app, in the Database section near the bottom, what does it report for how many projects, actions, and zip files you have? And what does the Finder report for the size of your Documents/OmniFocus.ofocus file on your MobileMe volume?

Best solution, IMO, is to call up the support ninjas at 1-800-315-OMNI between 10-5 Pacific time and get their help with sorting out the issues.
