Fwd: Code Optimization Help

[Joseph Crawford <codebowl@xxxxxxxxx>]

Hello Everyone,
 
I have some code that is using COM to interact with MS Word to create a mail 
merge based on my mysql database, however it is running dreadfully slow 
13.53846 seconds to be exact. This is only running on 34 records, i could 
imagine running this on a few hundred records not to mention thousand. Is 
COM usually this slow? These load times i believe to be accurate as they 
come from zend studio's profiler.
You can see screenshots of the profile @ 
http://codebowl.dontexist.net/bugs/MailMerge/ Below you will see my code, 
anything you guys see that i could do to speed this up quite a bit i would 
appreciate it. It seems the naughty methods are CreateHeader, 
CreateDataSource, CreateDocument.


CODE
