When monitoring a high speed communication link, Docklight consumes 100% CPU time and seems to freeze.

When monitoring a high speed communication link, Docklight consumes 100% CPU time and seems to freeze.

Applies to: Docklight (all versions), Article ID: dl_prb001

Possible cause: The Docklight processing speed is too low to keep up with the amount of data received. Most of the processing time is consumed for the visual formatting and display buffer updates.
Several options are available to increase processing speed.

If you do not need to highlight the different communication directions in different colors, try “Plain Text Mode”. In many cases, the decimal or binary display is not needed, so disabling these communication window representations will result in better performance as well.

See also the section “How to Increase the Processing Speed …” of the Docklight User Manual.

NOTE: Docklight / Docklight Scripting V2.1 and higher switch to “Plain Text Mode” automatically when detecting overload situations. The V2.1 versions are also considerably faster and the (free) update is highly recommended.
