I have an OPC client receiving data from the OPC server that is installed as part of NIDAQ and am finding the performance unacceptable.
The client is used in another application to receive updates to 256 channels at 70Hz from a non NI OPC server over the network using DCOM and in this case the client shows about 1% processor usage and the server about 3%.
With the NI OPC server I get about 2% processor on the client and 60% on the server and am limited to about 2Hz update rate with only 6 channels configured.
I know the client is OK - any ideas how I can get at least 20Hz out of the NI OPC server?
PS. Is this the correct place to ask this question? - there dosen't seem to be a place for NIDAQ questions.
