Call WebService Node --->

We are calling a WebService using the Call WebService Node.
We are creating several instances of that Node about 100 using Multi Node Instance Concept and calling the WebService about 100 times parallely.

So a 100 calls are made parallely.

It seems that the WebService takes a long time to respond in this case.

With one call, it takes a few secs but with 100 calls running parallely it takes anywhere between 1 min to 3 mins.

Is this a problem with the WebService or with Multi Node Instance Concept with Multiple Instances of the same Node running parallely and that the Node is waiting for All Instances to Complete and then move forward?

To the last part of your question (is the web service node waiting for all calls to complete) - this is an option available under the other tab when you run MNI. The other tab also has an option to run all instances at the same time or to run them one after the other.

I already do RUN ALL INSTANCES at the same time which I believe is parallel execution?

Correct me if I am wrong?

But I still see the delay?

Assuming you have the web service node configured to complete only after all the instances are completed, you should time how long it takes when you do 25, 50, 75, 100. If the time to complete takes longer, then start looking at the server performance on the app server and web service server.
