| Area | Limitation |
|------|-------------|
| UI polish | Outdated, clunky compared to modern BI tools. Steep learning curve for bands, expressions, and parameters. |
| Charting | Basic out-of-the-box charts (jFreeChart). No native interactive visuals like Power BI. |
| Collaboration | No built-in version control for .jrxml files (though you can use Git on the XML files). |
| Self-service BI | Not for ad-hoc drag‑and‑drop analytics — requires designer to build reports. |
| Mobile design | Responsive layouts require manual work (no automatic mobile preview). |
A report that takes 5 minutes to run is a failed report. Here is how to get the best speed. Even the best tools can be misused
| Problem | Best Solution |
| :--- | :--- |
| Report runs too long | Use $XEQUAL, ... instead of LIKE with leading wildcards (%text%). |
| Memory overload | Enable Virtualizer (File > Properties > Report > Virtualizer). Use JRFileVirtualizer to swap to disk. |
| Static text eval loops | Set isStretchWithOverflow="false" on non-text fields. |
| Subreport hell | Convert subreports to Table components for vertical datasets. |
Set Language in report properties to java (faster, easier to debug). | Area | Limitation | |------|-------------| | UI
