This probably depends on what CPU someone has, someone with a higher-end CPU (higher-IPC/higher clockspeed) probably will have a better experience.
On older/lower-end CPUs it is more common to see when something is single-threaded especially when it's also interpreted. Particularly any type of generator/loader, filter, renderer, live audio. Which to be clear, is from a user perspective.
