profiling valgrind itself

Can we measure the ratio of time it takes to run a program natively and under Valgrind?

then

time valgrind myprogram

And some basic calculation ;)

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.
