 ===== UniFi Dream Machine Platform Notes =====
   * UDM appliances have built in UniFi controllers and cannot be adopted by external controllers.
   * Multiple sites are no longer supported on UDM platforms.
-  * The built-in 8 port switch as a total switching capacity of 1 Gbps
+  * The built-in 8 port switch supports non-blocking throughput of 16 Gbps (1Gbps full duplex across all ports), but only has a 1 Gbps CPU uplink.
+    * Inter-VLAN routing throughput is limited to 1Gbps.
+    * Intra-VLAN throughput is line-rate.
+    * The 2.5Gbps link only applies to rev3.1--not newer revisions.

 ===== Getting Started =====
-  * In order to install Protect on the UDM-Pro, a hard drive must be installed and the machine rebooted.
+   * Since 1.8 Protect is automatically installed and won't need hard drive to run. Without hard drive you can adopt cameras and check video feed but no recording features are available.
-    * WARNING: All contents of the hard drive will be deleted once the UDM-Pro is rebooted and the drive is initialized for the first time.
 ===== Known Issues =====
@@ Line 81: / Line 89: @@
   * Speed Tests run from the controller on the UDM-Pro show inflated numbers and are not reliable at this time.
 ===== Troubleshooting tips =====
+ **High RAM usage, or kswapd using too much CPU**
+This is likely due to Java and/or Mongod using too much memory
+  * You can reboot the entire UDMP , or
+  * ''unifi-os restart'' which will restart the container running the controllers
+  * ''unifi-os shell'' and ''etc/init.d/unifi restart'' then  to restart the controller directly.
