+## Disable docker userland proxy
+
+When Lancache is configured with high performance storage it is possible to become CPU bottlenecked. When this happens it might be beneficial to disable the Docker userland proxy. This is done by creating the file `/etc/docker/daemon.json` and adding:
+```
+{
+    "userland-proxy": false
+}
+```
+Then restart Docker.
