High Memory and CPU overhead is incurred at the moment of Snapshot capture. The overhead rises up to 15-40% depending on the application.
The measurement mode is Sampling with heap and all the allocation recording are turned on.
The problem is more severe with High Resource(Memory and CPU) intensive applications.
Similar problem is noticed with Java profiler agent too.
