We run IronPDF in background jobs to generate thousands of reports per day, and it has performed well once we aligned it with our high-volume architecture. After introducing concurrency limits and queue-based processing, performance became consistent and predictable, even under heavier loads. From an operations context, that level of stability is essential. One thing to be aware of is that rendering output can differ slightly from browser output, so some HTML templates need adjustment to match the desired visual result.
