Instruments : Instruments can be used to show the FOLLOWING

• CPU Usage
• Disk Reads and Writes

• Thread activity
• Network statistics etc

Shark: Traces function calls and graphs memory allocation.

Big Top: Graphs performance trends.

Spin Control: Gathers information about what the application was doing when the rainbow spinner appeared.

Malloc Debug: Shows how much memory the application is consuming and which functions ALLOCATED LARGE amounts of memory. Also helps find leaks by finding allocated memory that is not REFERENCED anywhere in the program.
