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

Hello,

I am experiencing repeated short freezes on the EUREX feed, specifically affecting the DOM on the FESX.

Description of the issue:

The DOM freezes for roughly 1–2 seconds every ~5 seconds

Between freezes, everything works normally

This happens consistently and is very noticeable during active markets

What I have already checked:

Switched between the standalone DOM and Chart Trading DOM → same behavior

Chart drawing time is stable, typically 13 ms to 27 ms

No other performance issues visible

Only one instance of Sierra Chart running

Only one chartbook open

Chartbook contains 23 charts including the DOM

Environment:

Single SC instance

No other chartbooks

No heavy studies being added or removed during the freezes

Given the regular timing and the fact that chart drawing times stay low, this does not look like a local performance bottleneck. It feels more like a short data pause or feed-related lag.

Could you please check if there is any issue or instability with the EUREX data feed at the moment, or advise what additional diagnostics I should run to help pinpoint the cause?

Thank you.
