I attached a text file (hopefully it gets through).cat-ing this file takes ~18 sec. But with enter, it takes just ~3 sec (these measurements are done with the console version). It behaves like this 100% of the time (it's a more reliable test than the "seq" test).
And it also speeds up, if I don't press enter, but constantly move the mouse (using the X version).
It seems that emacs waits for some kind of event here (hence the low cpu utilization). But if there's some event (mouse, or an unprocessed input), then it speeds up (and uses 100% cpu).
