+### How to move the appdata folder from the datadir to an ssd to improve the performance?
+If the datadir in your setup is configured to be placed on an HDD or network FS like SMB or NFS, you can follow the steps below to change the location of the appdata folder to be located on an SSD in order to improve the performance of the setup.
+
+> [!NOTE]  
+> The following steps only work if you already configured and used NEXTCLOUD_DATADIR as mentioned [two sections above](#how-to-change-the-default-location-of-nextclouds-datadir). 
+> In this example here, we assume that you used `NEXTCLOUD_DATADIR="/target/path/`.
+
+After the initial installation is done and all datadir files of Nextcloud are stored inside the configured `/target/path` directory, you will also see an `appdata_*` folder in there that stores app-related data. You can now move that folder to a faster SSD if the target dir is not already positioned on an SSD by first using `rsync` to sync the files a location on an SSD. Afterwards rename the appdata folder in the datadir to something like `appdata_*-backup`. Afterwards add the following line to `/etc/fstab`:
+```
+/source/path/on/ssd  /target/path/<appdata-path>  fuse.bindfs  force-user=33,force-group=33,allow_other  0  0
+```
+Do not forget to adjust `<appdata-path>` to the correct `appdata_*` name that your installation initially created automatically.
+
+Then use `sudo mount /target/path/<appdata-path>` to mount it directly.
+
+Afterwards things should be speed up.
 
 ### How to store the files/installation on a separate drive?
 You can move the whole docker library and all its files including all Nextcloud AIO files and folders to a separate drive by first mounting the drive in the host OS (NTFS is not supported and ext4 is recommended as FS) and then following this tutorial: https://www.guguweb.com/2019/02/07/how-to-move-docker-data-directory-to-another-location-on-ubuntu/<br>

 ### Can I run this with Docker swarm?
 Yes. For that to work, you need to use and follow the [manual-install documentation](./manual-install/).
