 A modern CPU should be able to keep this value below 50ms plus the TCP connection latency. TCP packet drops can cause this value to increase more dramatically.

 Is identical to the server latency above, but it is measured by the server to the client instead.

+== Batch Delay ==
 This value represents how long the server waits for window updates to accumulate before actually processing them and sending them to the client.
 This value changes dynamically to try to provide the best framerate without flooding the connection with compressed pixel data.

+== Damage Latency ==
+This value represents the time it takes to:
+* retrieve the pixels from the window
+* compress them
+* submit them to the network protocol layer
+* pass them on to the operating system (which still has its own network buffers - though we do set the {{{NODELAY}}} socket flag, so this should be fairly small)
+
+This is the step that happens after we have waited for the batch delay above.
+
+
+== Encoding Quality and Speed ==
+This value applies to the video encodings, {{{jpeg}}} and {{{webp}}} encodings.
+When using a video encoder, we may also send the same area again using a lossless encoding as part of the "automatic lossless refresh".

+== Decoding Latency ==
+This figure represents the average time it takes for the client to decompress the screen updates it receives and update the window contents with it.
+
+
+== Regions/s ==
+This is the number of screen updates per second.
+Bear in mind that those updates may be very large or very small, and anything in between..
+
+
+== Pixels/region ==
+This is the average size of the screen updates the client is receiving.
+
+
+== Pixels/s ==
+The total number of pixel updates displayed per second.
