tesseract 4.1.1 slow in aws instance centos7

[James Lian]

Hi all,

i have installed tesseract 4.1.1 to aws instance centos7.

We have noticed that there is slowness in comparison to our personal laptop.

Is there anything i can do to run faster?

The  ec2 instance is having 4 vcpu and 16gb memory

tesseract 4.1.1

 leptonica-1.78.0

  libjpeg 6b (libjpeg-turbo 1.2.90) : libpng 1.5.13 : libtiff 4.0.3 : zlib 1.2.7 : libwebp 0.3.0

 Found AVX512BW

 Found AVX512F

 Found AVX2

 Found AVX

 Found FMA

 Found SSE

Are these version information from the server or from the laptop?

General rule: use the latest stable version (5.2, 4x is unsupported)

In my  Oracle Linux Server 8.6  max version available is tesseract 4.1.1, in my spring boot microservices in pom.xml :

       <dependency>
            <groupId>net.sourceforge.tess4j</groupId>
            <artifactId>tess4j</artifactId>
            <version>4.3.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.pdfbox</groupId>
            <artifactId>pdfbox</artifactId>
            <version>2.0.22</version>
        </dependency>

It's slow  PDDocument.load (org.apache.pdfbox.pdmodel)  either Tesseract.doOCR

Thanks
