Asana used to sometimes have textareas that would take a full three seconds to display each key press. On then-current MacBook pros. You know, something that had nearly zero latency on first-gen single-core Pentium chips. Hell it may still do that, I never saw them fix it, I just finally got to stop using it.
Never underestimate the ability of shitware vendors to make supercomputers feel slower than an 8086. These days it usually involves JavaScript, HTML, and CSS.
Please tell me this is a satire piece...
