Post From: Charts lagging on extreme active periods

Do you also realize, that our backend CME multicast feed processing is Sierra Chart. That is handling a very high data rate feed tracking anywhere from 3000 to 55,000 symbols per instance. And on top of that recording the tick by tick intraday data over a period of years for rapid serving. There is no lag whatsoever. It just does not happen.

Sierra Chart is the backend infrastructure for the Sierra Chart Exchange Data Feed serving over 500 realtime users at a time. There is no lagging.

And if there is any lag, it would not be in Sierra Chart itself, but really within our real-time server process, and that is primarily where the performance improvements have been made, by the removal of unnecessary symbol ID mapping. And those processes, handle anywhere from 50,000 to 250,000 symbols simultaneously and delivering data to hundreds of users instantly.

By comparison the TransAct network is basically about 200-300 symbols. So you can see just how fast and capable our software actually is. Drastically higher data rates and symbols, and no lag.

But none of this post, has any relevancy whatsoever to the TransAct data feed. We are simply referring to our own data feed. Other than the prior paragraph.

Update: 2019-02: We may have made significant performance improvements with market data processing and real-time data serving in our backend infrastructure. This is all running very optimally at this time but once again this is not related to the problem that you had. These changes, are there to ensure that there is not even lag within the millisecond range.
