# Raspberry Pi, and similiar
|
|
|
|
|
|
|
|
|
|
Both component can run next to each other on a raspberry pi or
|
|
|
|
|
similiar device.

There is a [project on
|
|
|
|
|
github](https://github.com/docspell/rpi-scripts) that can help with
|
|
|
|
|
setting up a raspberry pi with docspell.

## 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
|
2020-09-25 19:58:02 +00:00
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
virtual machine only had to host docspell (joex and restserver, but
|
|
|
|
|
the restserver is very lightweight).
|
|
|
|
|
|
|
|
|
|
The learning task for text classification can also use high amount of
|
|
|
|
|
memory, but this depends on the amount of data you have in docspell.
|
|
|
|
|
If you encounter problems here, you can set the maximum amount of
|
|
|
|
|
items to consider in the collective settings page.
