Hello! According to the FAQ[1], if I run tesseract on a multi-page image, it should process the pages in parallel.
I am converting a 10-page TIF (in one file) into PDF, and looking at *top*, it seems like tesseract never uses more than about 250% CPU (I have 16 cores / 32 threads on my machine). Am I doing something wrong? tesseract combined.tif out pdf Tesseract Open Source OCR Engine v4.00.00alpha with Leptonica Page 1 Page 2 Page 3 Page 4 Page 5 Page 6 Page 7 Page 8 Page 9 Page 10 OSD: Weak margin (6.98) for 914 blob text block, but using orientation anyway: 0 tesseract -v (from Debian Testing): tesseract 4.00.00alpha leptonica-1.74.1 libgif 5.1.4 : libjpeg 6b (libjpeg-turbo 1.5.1) : libpng 1.6.28 : libtiff 4.0.8 : zlib 1.2.8 : libwebp 0.5.2 : libopenjp2 2.1.2 Found AVX Found SSE Thanks!
