Description
Description
Currently, PDF generation with markitdown processes pages sequentially, leading to longer rendering times. By adding the ability to process PDF pages in parallel, we can significantly improve performance and reduce overall generation time. Please consider implementing parallel page processing support.
Current PDF Conversion Performance
| File | Size | Pages | Time (seconds) |
|---|---|---|---|
| Test_parsing_50MB.pdf | 50MB | 1113 | 34.64 |
| Test_parsing_20MB.pdf | 20MB | 598 | 9.23 |
| Test_parsing_20MB.pdf | 2MB | 23 | 0.27 |
