Sampling rate improvement

Open BhargavN02 opened this issue 1 year ago • 3 comments

Can anyone let me know how to increase the sampling rate of the data incoming? The data frequency at the server is around 20kHZ. The current subscription I'm using has a sampling rate of around 200Hz. Is this a restriction from OPC?

That is a limitation of hw and programming language. You may manage 200hz maybe 500 with c++/rust code. No way you will make 20khz. In python 100hz is almost the max maybe 50 with ua
