Raspberry Pi, and similiar🔗

Both component can run next to each other on a raspberry pi or similiar device.

REST Server🔗

The REST server component runs very well on the Raspberry Pi and similiar devices. It doesn't require much resources, because the heavy work is done by the joex components.

Joex🔗

Running the joex component on the Raspberry Pi is possible, but will result in long processing times for OCR. Files that don't require OCR are no problem.

Tested on a RPi model 3 (4 cores, 1G RAM) processing a PDF (scanned with 300dpi) with two pages took 9:52. You can speed it up considerably by uninstalling the unpaper command, because this step takes quite long. This, of course, reduces the quality of OCR. But without unpaper the same sample pdf was then processed in 1:24, a speedup of 8 minutes.

You should limit the joex pool size to 1 and, depending on your model and the amount of RAM, set a heap size of at least 500M (-J-Xmx500M).

For personal setups, when you don't need the processing results asap, this can work well enough.
