Why do you want to do measurements, if this isn't your domain?
Follow Len advices to reduce latency. There seldom is the need to
measure the exact latency.

Run

  sudo apt-get update && sudo apt-get install checkinstall

then instead of running

  sudo make install

try to use

  sudo checkinstall

don't forget to remove all packages that belong to jackd, such as
libjack-whatsoever, it's the policy of your distro to split upstream
into several packages, then install the build package by

  sudo dpkg -i *.deb

it might not work for jackd, but you could test it.

However, there's no reason to test jackd before installing it, you
always could remove it and reinstall the jackd related packages.
Also consider to backup your install, so if you should make extreme
mistakes, you could restore your install from the backup.

If you need to use

  sudo make install

then before doing this also remove all installed packages that belong
to jackd, before doing it too and after "make install" don't forget to
run

  sudo ldconfig

Ralf
