Jasper Report Very Slow In Internet Explorer

I have several Jasper reports that run blindingly fast in Eclipse, and just about that fast in Firefox, but when I run them in IE (which almost all of my users use; sigh) they run very slowly. A report that takes one or two seconds in Eclipse, and 2 or 3 seconds in Firefox, takes easily 20 seconds in IE. It varies a bit from computer to computer (some are better than others, maybe 5-10 seconds).

Any ideas what could be causing this, or how to remedy it?

I have narrowed down the place in the code where the delay occurs and it is definitely in this function call:

JasperCompileManager.compileReport

which of course is compiled code that can't be diagnosed further.

Please help if you can! Much thanks, and don't step in the moose chips.

Are there lots of nested tables? IE is notorious for slow-downs dealing with deeply nested tables.

Some table nesting, but not a tremendous lot.

Does IE have its own Java engine? Why would it be slow only in IE, but not in Firefox or Eclipse? Wouldn't they all use the Java you have installed on your computer?
