Can we quantify "inefficient"?

The link you have there shows that the direct array manipulation 
approach on the system that was tested can convert a 1015-char string to 
an ArrayBuffer and back about 30k times per second in a modern browser. 
  Are we expecting people to be pushing ~30MB of cue data per second 
through conversions to strings?
