With an old computer, I would definitely use a distribution that provide the rt-sources with the cgroup functions disabled. It have the advantages of being much simpler, and simpler to manage, than a systemd/cgroup realtime audio based setup, and to not include that paranoid crap wanted by big corporations. Also, I would compile my own kernel from the distribution's kernel and change its processor config to correspond to the processor of the machine. This alone will give you a speed boost of around 10%. You must install the kernel sources corresponding to your kernel, along with its .config file. When done, run make oldconfig make menu config In it got to "Processor type an features" ---> "Processor family" and change it for the best optimisation for your hardware. Save the config, exit, compile and install the kernel by following the procedure of your distribution. It's intimidating the first time, but in fact quite easy.
