Being a native-code game engine developer is useful perspective - having to spit out millions of triangles, pixels, and audio buffers within a 16ms frame budget teaches you just how powerful modern computers really are. You think (and work) in microseconds, where if something takes a millisecond you stop and investigate what the hell is wrong (e.g. an XInput bug in my game Weapon Hacker blocked for 500us every frame).
From that perspective, not being able to generate a blob of basically static HTML text in 600ms (100 requests per minute according to the article) seems insane.
