Performance Bottleneck Analysis
Conversion speed is mainly affected by CPU/GPU performance, number of PDF pages and image complexity. Benchmark tests show that: ordinary CPU takes about 3-5 minutes to process 10 pages.
Speed Up Program
- hardware acceleration: Modification
device="cuda:0"Enable NVIDIA GPU (CUDA driver required) - batch file: For multi-chapter catalog PDFs, it is recommended to merge the files after conversion.
- parameterization: Settings
extract()(used form a nominal expression)skip_images=TrueSkippable image processing
Advanced Techniques
- Linux systems can add
OMP_NUM_THREADS=4Environment variable to control the number of threads - The model is memory-resident after loading and is suitable for use with
while TrueLoop Continuous Processing of Multiple Files - Very large files (>50MB) are recommended to use first
