Hi, I'm experiencing an issue where sierra charts freezes for 10+ seconds at market open. Please see video link. I saw a similar post here: Sierra chart data service lagging on market open video: https://imgur.com/a/H9bqh9n heartbeat log: SC Data - All Services | Heartbeat from server | ServerReceivedClientHeartbeatSecondsAgo=9, NumberOfOutstandingSendBuffers=0, TransmissionDelayInMilliseconds=0, ServerSendBufferSizeInBytes=0, ActualMessageDelay=0.1 seconds | 2020-09-16 08:29:43.135

We are aware some users are experiencing this. And we are working on a solution. It does relate to network connectivity and the large amount of data transmitted. What we are working on is data compression. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

How much of a pause? The log does not indicate any pause. It must have been between the 10 second heartbeats. We have determined with 100% certainty, these issues are user specific connectivity specific issues. It does not mean it is with your ISP but somewhere along the path of connectivity. The data compression we are implementing, will help. That is the only other thing that we can deliver which would help. Allow about another 2 to 3 weeks for that. And for the record, we do not observe this problem in our testing. We have tested extensively over the last week. No delays, no pause no stopping, no problems at all. And testing within the US, and a remote connection in Auckland. The servers are delivering the data without any lag at all. And ultimately users need to realize we cannot solve Internet connectivity issues. The compression is the very last thing that we can do and it should help. If you still have a problem, try a different Internet connection. The other thing we are going to do is set up another data relay on the West Coast of the US. Not sure where you are located but that would be available. We should have this out in about a week. Sierra Chart Support - Engineering Level Your definitive source for support.

here's a video of it. this might be an unrelated issue though as you can watch the entire program freezes this time including the clock. https://imgur.com/a/nwGcjaf |

Recently, I am seeing the lag at open also (Denali). I use to never any lag at all until lately. Now it seems like a few seconds then ok after that.(now on version 2168). Seems like something changes in the past few releases and then was supposedly fixed but I'm still seeing it. Since I was never seeing the delay at open before, I was wondering if the new SCDateTime class changes might have had something to do with it because i never had any issues before these latest releases. I occasionally trade the open but now I don't feel I can with the sometimes delay at the open. In any case, I guess we are waiting on compression to be implemented next to possible address the opening lag?

as you can watch the entire program freezes this time including the clock. This is a performance issue in Sierra Chart and is unrelated to the data feed. For help with this, refer to:High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often Regarding post #7, the compression will be the definitive solution. We should have that out this week. Refer to: Data Feed Stopping/Lagging Issue (non-Denali specific) We think the reason some users notice a problem lately is due to increased bandwidth, due to millisecond time stamping. And changes with the receive side network socket buffering. Both of these issues are being addressed. The buffering issue is non-Denali data feed specific.
