The `-change-duration=` option specifies the amount of time how long the `mtredisalize` server should aggregate
changes made to the world before reporting them to `mtwebmapper`. It defaults to 30 seconds but the value can
be increased or decreased depending how often you want to update the map. Decreasing it will increase the
computing pressure on your system so configure it wisely.
## Pre-compute the map tiles with mtseeder
**TODO: Write me!**
Even in a dynamical Mintest world played with many players most of the data is static over time. To generate
a basic map to apply only changes to use `mtseeder`:
GOMAXPROCS=6 mtseeder \
-colors=/path/to/your/colors.txt \
-output-dir=/path/to/your/map \
-workers=3
This contacts the `mtredisalize` server running at localhost port 6379 to fetch the block data from. You will
need a `colors.txt` to map the block nodes to pixel colors of your map. The repository contains
[one](https://bitbucket.org/s_l_teichmann/mtsatellite/raw/default/colors.txt). See `mtseeder --help` for
all options.
The `-workers=` option and the `GOMAXPROCS=` environment variable are completely optional but very useful
to exploit multiple processor cores on your machine. Set `GOMAXPROCS=` to the result of `nproc` and `-workers=`
to a number a little lesser. You have to experiment with this to find a good setting.
Even with good CPU usage generating the map and overview image tiles take a while.
Tip: A lot of the Minetest map tiles are white/empty but are saved as dupes in the file system. To
deduplicate them you can use e.g. [hardlink](https://bitbucket.org/s_l_teichmann/hardlink). You
can also run it as a nightly cron job to dedupe the map on a regular basis.
