Using the Profiler Panel

The profiler panel shows all your profiled methods in one place. Here’s how to use it effectively.

Panel Layout

Toolbar

The top bar contains:

• JVM Selector — Choose which Java process to profile
• Refresh — Update the JVM list
• Health — Check system status

Methods List

The main area shows all profiled methods with columns:

Column	What it shows
Method	Class and method name
Avg	Average execution time
Max	Maximum execution time
Calls	Number of invocations
Trend	Performance change

Status Bar

The bottom shows:

• Profiling status (Active/Stopped)

Sorting Methods

Click any column header to sort:

• Avg — Find your slowest methods
• Calls — Find your most-called methods (N+1 query detection!)
• Trend — Find methods that are getting slower

Click again to reverse the sort order.

Navigating to Code

Double-click any method to jump directly to its source code.

The IDE opens the file and positions your cursor at the method.

Tips

Keep it Visible

Dock the panel next to your editor for constant visibility

Sort by Avg First

Start with slowest methods — they have the most optimization potential

Watch for High Calls

High call count + low time often means N+1 queries

Check Trends

Rising trends (↑) mean something changed — investigate!
