Hi to all, I have implemented a Spring boot microservice which use tess4j 4.3.1 and pdfbox 2.0.22 in my server Oracle Linux Server , example code https://colwil.com/how-to-extract-text-from-a-scanned-pdf-using-ocr-in-java/ When I execute code with my IDE on windows pc and invoke local service, time execution is fast : "Tesseract.doOcr" 8 seconds, so when I execute api to invoke microservice's code method "Tesseract.doOcr" is slow 40-50 seconds, parameter pdf file is the same Any idea? Thanks :-)
