What's new in 4.1?

Improvements to memory, waits, forced plans & slow queries tabs

Memory Analysis Enhancement

The Memory tab now displays maximum, average, and minimum values alongside current readings. This historical view makes it easy to identify memory clerk issues that occurred during your selected time range, even if they’re not currently active.

Memory tab improvements

Waits Visualization

The Waits tab now includes the waits bar chart, previously only available on the Performance tab. This consolidates all wait analysis tools in one location for a streamlined troubleshooting workflow.

Waits tab improvements

Flexible Form Management

Forms can now be configured to either close existing instances when opening new ones (default) or allow multiple instances to remain open simultaneously. Quickly load new form instances without the extra step of closing the existing form. Or keep existing forms open to refer to later or for side-by-side comparisons.

Single Instance Forms
