Running the joex component on the Raspberry Pi is possible, but will
result in long processing times for OCR and text analysis. The board
should provide 4G of RAM (like the current RPi4), especially if also a
database and solr are running next to it. I recommend to give joex a
heap of 1.5G (`-J-Xmx1536M`). You should also set the joex pool size
to 1.
When joex processes the first file, some models are built loaded into
memory which can take a while. Subsequent processing times are faster
then.
database and solr are running next to it. The memory required by joex
depends on the config and document language. Please pick a value that
suits your setup from [here](@/docs/install/running.md#memory-usage).
For boards like the RPi, it might be necessary to use
`nlp.mode=basic`, rather than `nlp.mode=full`. You should also set the
joex pool size to 1.
An example: on this [UP
board](https://up-board.org/up/specifications/) with an Intel Atom
x5-Z8350 CPU (@1.44Ghz) and 4G RAM, a scanned (300dpi) pdf file with 6
pages took *3:20 min* to process. This board also runs the SOLR and a
postgresql database.

The same file was processed in 55s on a qemu virtual machine on my i7
notebook, using 1 CPU and 4G RAM (and identical config for joex). The
