Well i have approximatelly 3000 customers at the moment for our software. We are using lots of invoices to OCR i.e. 1 customer uses approx 10.000 documents a month. So opensource is worth it. I want tesseract, sinds it is free to use. I believe opensource is the future.
So, can somebody help me optimize it. With lots of CPU usage i mean when it needs to use more CPU for some parameter like "super quality". I want to use that parameter.
