When rendering a
List
, eachListItem
would be cloned. Removing the clone, and replacingWidget::render
withWidgetRef::render_ref
saves us allocations caused by the clone of theText<'_>
stored inside ofListItem
.Based on the results of running the "list" benchmark locally; Performance is improved by %1-3 for all
render
benchmarks forList
.
