_Realtime performance window_

The performance window is a monitor of internal workloads and a debug tool. It has two different modes, **Realtime** and **Draw**. As default it opens in realtime.

It is a monitor of the workload of the desk. The first six rows are incoming traffic and the last rows are outgoing traffic.

The different loads have different colors:

- Red - DMX data
- Green - MA Net feedback
- Blue - Station feedback (MA stations = 1 ms / Windows > 1 ms)
- Yellow - Network Protocols

The lines on the left side of the view are showing tasks with a high calculation priority. The lines on the right side shows tasks with a normal priority.

The small line that are only 2 rows high, show traffic via USB connections (Command and Fader Wing for example) while the long lines that are 8 rows high, show traffic via ethernet or DMX.

The traffic for incoming USB connections are on line 7 and 8, while outgoing USB traffic is on line 9 and 10.

If the yellow lines (Art-Net traffic for example) are shown side by side in the lower part, then there is a delay on the outputted universes. To adjust this delay go to Setup - Network – Network Protocols and adjust the Delay column.

There are two buttons in the upper right corner of the Performance window

- Pause freezes the display
- Realtime/Draw switch the window between **Realtime** and **Draw​**
