I created a large (1800 page) multi-page tiff and am feeding it to Tesseract via command line (on Ubuntu). This way I am testing Tesseract performance. I am still getting about 5/6 PPM. I will run the test on another machine to see if the performance is the same. Is this the performance that you are seeing for similar pages (details in thread above). This is about 25% the performance of a commercial engine that I am evaluating (it gets about 24 PPM with 2 cores on my laptop), and its accuracy is significantly better.
