With realtime kernel it doesn't get same or better latency as pulseaudio

"I recently tested pipewire with an application that normally uses pulseaudio and requires a realtime Linux kernel to meet acceptable levels of latency, and I found that with the same latency settings, pipewire was not as responsive as pulseaudio. Perhaps I needed to configure pipewire differently to achieve the same (or better) latency as pulseaudio, but out-of-the-box (for me), that did not seem to be the case."
