Jasper Reports Very Slow In Internet Explorer

[darelatlexon]

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.

One suggestion here, its better to have compiled reports in your project and just fill them at runtime.

Hey darelatlexon,

 

As jawwadfarooq1 said earlier, its better to have compiled report files in your workspace and also if report data is huge Virtualizer.

 

Thanks,
