PyReportJasper very slow with CSV file

[thibault-chausson]

Hello,

Describe the bug

I just tried your library to generate an XLS file with Jasper. I input a 2MB CSV file, and it takes a few seconds to generate, but when I switch to a 22MB file, it's impossible to generate the file.

As a result, I tried with the Java version, and the generation takes very little time for the 22MB file.

Could you inform me if there is another solution?

Desktop:

• OS: Windows 11
• Python version 3.11.5
• Library version 2.1.0
• Java version17.0.10
• JVM Oracle

Thank you for your help.
