In my rails application, certain computers were having huge problems.  
There were certain pages that were exceptionally slow, even to the point  
of timing out. Other computers did not have a problem. I finally found  
that Firefox was the difference. When using Firefox on those computers  
it works fine. The slow pages were typically posting a form with a  
couple hundred fields.

This behavior was the same with the rails server running on Windows,  
Ruby 1.8.2, Apache2, FastCGI and also on Linux, Ruby 1.8.4, Lighttpd,  
FastCGI.

Any ideas what would cause this?

Nah, probably just the symptoms checklist on the IE “report bug” form.

He must be working with the IRS to do online tax form submission.

You’re confusing reading a file and rendering it. Indeed the file is  
at most 4-5 KB, but the amount of rendering and handling events  
(input, ?) from the fields is quite intensive. Clearly IE has  
problems with this.
