From the doc it appears that invoking the -g/-pg option will cause the program to run "slower than normal". Also, it appears that gprof can't provide real-time feedback to the process.

Anything you add to monitor your process is going to make it run "slower than normal". Why is it that you need real-time feedback?

Some overhead is okay, but it would be nice to have as minimal impact as possible. The reason im looking for realtime feedback is because there are some components of the program that are "soft realtime" constrained and it would be nice to defer/kill some tasks if the cpu is overloading
