Hi:
I am a user of libunwind. I am developing a profiling system, "Bianque".
I use libunwind to unwind the stack on the target machine. But the time
cost is too expensive.
While the layers of call chain is 130 and the stack size is 1MB, we need
3.8 milliseconds to unwind it.
My CPU is Xeon(R) CPU E5-2430 0 @ 2.20GHz.
Is this cost normal?
Regards
Chenggang
