Deprecated to enable the event thread according to Java Servlet Specification that may prohibit the creation of new threads

[Default: false]

[Default: true](disabled)

It specifies whether to disable the use of the event processing thread. If disabled, no event processing thread will be used at all. In other words, all events are processed in the same thread that serves HTTP requests (so-called Servlet thread) directly.

For better performance (and better compatibility with other frameworks), it is recommended to disable the use of the event processing thread. Please refer to ZK Developer’s Reference: Event Threads for more information.

Enable the event thread only if the project does not need to integrate other frameworks (such as Spring), uses org.zkoss.zul.Messagebox and modal windows a lot, and does not have a lot of concurrent users.
