Enable downloading debug information for system kernels by installing debug info packages available for your system version.

Enable downloading debug information for the application binaries by using the

-g

option when compiling your code. Consider using the recommended compiler settings to make the performance analysis more effective.

Build your target in the

Release

mode.

Create a baseline against which you can compare the performance improvements as a result of tuning.

For example, you instrument your code to determine how long it takes to compress a certain file. Your original target code, augmented to provide these timing data, serves as your performance baseline. Every time you modify your target, compare the performance metrics of your optimized target with the baseline, to verify that the performance has improved.

Build and install the sampling drivers, if required.

For remote analysis, configure SSH connection and set up your remote Linux system depending on the analysis usage mode.
