Currently we are communication over the webapi of the coresight server: is this the correct way?

 

We are starting with using WebApi for communication with PI.

 

For the webapi call:

How do we get the current values or a value at a specific moment
in time for multiple (say 50) points in one call.

We can get a list of points and then iterate through them and get the value (stream) using the webid of
each point. This is not very efficient given the request time of three seconds (3 sec per call).

 

In fact we are struggling with the WebID. Untill now all of our communication was based on tagnames.

What best practise is available?
