Character extraction in EnginesPool is slow

In the sample EnginesPool, extracting characters after OCR is slow.

Normally, OCR sample RecognizedTextProcessing is fast, so we want to have the same level of speed.

How can I solve it?

 

■Target file

 Demo.tif

 

■Comparison of processing time

 RecognizedTextProcessing → Avg0.18s

 

 EnginesPool → Avg15.2s

 

■Character extraction method

 Implemented in EnginesPool using "calculateStatisticsForLayout" of RecognizedTextProcessing

    Someone can explain how to improve the phenomenon that text extraction becomes slow when using EnginesPool because the support of ABBYY Japan isn't useful.
    help me.
