Post From: SierraChart/CQG lack of datafeed speed in the DOMs

Multiple threads in here already about increasing DOM performance.

Step 1 would be checking the Chart Update Interval under Chart > Chart Settings > Display > Chart Update Interval in Milliseconds

0 is global which is 500ms by default I think - way too slow for a DOM but fine for general charting I guess.

I use 20ms for my Primary and Fast Markets (think NQ or CL), everything else sits on 50ms.

There has been a lot of research into perception speed - some studies suggest as little as 13ms is possible for the human brain to interpret an image, others suggest 50-60ms in normal light conditions is best case.

There is an argument for having DOMs in a separate Instance as well, in my personal use I have found this unnecessary, but depending on your use case you may find beneficial.
