Post From: EUREX DOM freezes every ~5 seconds (1–2s lag) despite low chart draw time

Thank you John, I appreciate the clarification and the continued guidance. As a next step, I have taken things further and opened a completely separate Sierra Chart instance dedicated only to execution. This instance now contains just two DOMs, one for DAX and one for FESX, and no regular charts at all. At this point there are no remaining charts that could create cross-chart references. In this DOM-only instance I have: Removed all invalid and legacy symbols Cleaned up and eliminated all DLL related issues Eliminated all cross-chart references (there are only the two DOM charts) Disabled chart drawings, study collections, and chart linking Reduced market depth levels and internal depth calculation scope Minimized historical data loading and trade statistics Disabled anything not strictly required for DOM execution I have attached the current message log for reference. From what I can see, it is now clean. Despite this very minimal setup, I am unfortunately still seeing a small but noticeable lag on the DOM. It mainly occurs when offers are lifted or bids are hit. Occasionally it takes a second or two, sometimes slightly longer, for those hits and lifts to visually update. I am confident this reflects a data delay rather than just rendering, as I am running a NinjaTrader SuperDOM alongside Sierra Chart on the same machine and can observe the difference in responsiveness during aggressive buying or selling. I am not complaining and understand there are multiple factors involved, including the data feed and trading service. At this point I am simply trying to confirm whether there is anything else on the Sierra Chart side that could still be checked or adjusted, or whether this behavior is within what would be expected given such a minimal, isolated setup. Thanks again for the continued help and for taking the time to review this.
