Post From: Charts updating slow on live data, blasting fast on replay (Denali)

Set Remote Buffer Delay Send Time in Milliseconds down to 1 and reconnect to the data feed.. You must always reconnect to the data feed.

And then you can observe with the heartbeat logging, what the actual transmission delay is. It will go up based upon the number of outstanding buffers. There is one adjustment we will make with this last part, which will go into affected this evening.

If you notice there are outstanding buffers of 3 or more, then it does indicate a poor return path, for IP acknowledgments. If you are frequenting noticing something like 5 or more you have a poor quality Internet connection. The higher number of outstanding buffers, the more degraded the Internet connection is.

And you also need to realize, the lower Remote Buffer Delay Send Time in Milliseconds value that you use, you introduce potential for lagging and stopping data due to too many small packets.

Also please note this laggy behaviour on live data has nothing to do with the time of day or current market activity. It's same laggy in the us session and in the middle of the night.
Of course there are going to be fewer updates because the market is not active at these times or whenever it is less active. There is nothing wrong here at all. Nothing at all. We are not going to say anything further about this.
