I am trying to diagnose why my Denali Eurex feed is lagging and hope you might offer some suggestions. I have tried many of the solutions on the message board with no success yet. It is not a new issue and I am unclear whether it is a Sierrachart question or not so please bare with me. From approx. 3:20am EDT the lagging problem occurs whereby there can be no data intermittently for 5-10 seconds on either dax or stoxx. The dax and stoxx data is intermittently out of sync at that time too. As I am geographically challenged (New Zealand), I suspect the proximity to servers is the issue. Some technical info: Speedtest to Chicago is dn:597.11mbps up:4.85mbps. Computer is highly spec'ed and 6 months old. -Task manager doesn't break a sweat with Sierracharts and I have never had any issues regarding hardware. I use a small app (network time) that corrects any computer clock issues daily and the 'data delay' function on the chart header shows no issues. I do not have other chartbooks open and the chart studies are not excessive. (Chart drawing time is approx. 14ms, calculations per second is approx. 3) A snapshot from the server log (with heartbeat monitor turned on): 2024-02-12 03:54:50.125 | Denali Data Feed (Market Orders Data) | Heartbeat from server , ServerReceivedClientHeartbeatSecondsAgo=19, NumberOfOutstandingSendBuffers=0, TransmissionDelayInMilliseconds=20, ServerSendBufferSizeInBytes=0, ActualMessageDelay=-0.1 seconds, DataCompRatio=1.03, UncompressedBytes=64453, CompressionTime=0.015351(secs), NumCompressions=869, Source=10.201.90.5, MaxSendBufferSize=154, MaxSendBufferSizeDateTime=2024-02-12 04:06:13 This was the highest I saw 'ServerReceivedClientHeartbeatSecondsAgo' yesterday. It normally fluctuates between 10-17. |
