Hey there,

Thanks for reporting this.

From an initial look, this is not related to client-mvvm, since the slowness is not related to a binding being fired.

In fact, the page loads much faster with client-mvvm compared to regular mvvm (which is where the binding happens). and both client-mvvm and regular mvvm have the same processing time when searching an item.

Instead, this is regular performance of the search function of the searchbox, which is quite slower with a large dataset.

I've posted a ticket to review the performance for searchbox with large dataset: https://tracker.zkoss.org/browse/ZK-5602
