What do you dislike about Valgrind?

valgrind will slow the program execution. Realtime operation can be tested with valgrind since it slows down operation. Most of the time execution with valgrind for real cases cannot be tested.

Recommendations to others considering Valgrind:

Use along with massif, it will help find runtime heap usage. It will help identify the peak heap usage of the program. Massif visualizer will provide the function which uses peak heap usage of heap. Massif visualizer can be installed on Ubuntu desktop. It will provide a graphical representation of heap and stack usage. Review collected by and hosted on G2.com.
