profiling valgrind itself

Can we measure the ratio of time it takes to r开发者_StackOverflowun a program natively and under Valgrind?

---

man time:

time - time a simple command or give resource usage

So, something like:

1. time valgrind --tool=foo ./bar
2. time ./bar

This will give you the total, user and system times for that command to complete. You can then do the calculation yourself.

I suggest you :

time myprogram

then

time valgrind myprogram

And some basic calculation ;)
