Yes, followed the link. As per the document "there is at most one thread to access the UI of a given desktop" This means all UI updates are done one after other only. So setting each 100 values using Range.setCellValues() is consuming few ms of time. Updating such 'n' no of values is delayed.

Looks like columns are getting updated serially (syncronously)

I see. Your point is "synchronously". Yes, it's expected because javascript only supports single thread running. Updating cells in a browser relies on javascript

Do you mean you want to implement your application logic in a thread separate from a servlet thread?

Please follow this https://www.zkoss.org/wiki/ZKDeveloper%27sReference/ServerPush/AsynchronousTasks

Then Call Range.setCellValues() in public void onEvent(Event event).

Does Executions.schedule() fulfill your requirements?
