The latest version of Zenbu for Craft (version 0.10.0) has seen its code reorganized to be cleaner and reduce the number of queries needed to display entry data. Development testing yielded an overall approximate 25-to-75% reduction in both execution time and number of queries. Of course, performance always depends on the number of entries and entry columns to display, but overall performance was improved.
A number of smaller, but still very nice features have also been added, such as the ability to hide the native “Entries” tab in the Control Panel, display the section name as a column in Zenbu, as well as is empty/is not empty searching (for simple fields for now).
