Delay in response opcClient.ReadMultipleItems

Hello.
  1. How many items are you reading?
  2. When using other OPC client, have you read PRECISELY the same set of items? (one slow item can influence the timing of the whole call)
  3. Are you truly using ReadMultipleItems, or is it ReadMultipleItemValues?
  4. Is the OPC Server and client on the same machine, or are they communicating via LAN?
Best regards

We are using OpcLabs.EasyOpcClassic libraries to read data from machine (weigh scale). The version we have is 5.21.101.1
After calling ReadMultipleItems() method it takes more than 7 seconds to get the response back. Checked the machine on marikon server and response is almost instant. Can you please help on this.
