Comment #13 on issue 265 by m.niloc: Slow pasting
http://code.google.com/p/yi-editor/issues/detail?id=265
Corey,
In my test there's no difference in runtime between vty 3.1.8 and 3.1.9, and
Graphics.Vty barely shows up in the profile: less than 10%. And it's
asynchronous so
this 10% isn't even on the critical path. Yi does perform rendering in a
thread
separate the editor actions - this is why adding a threadDelay to
Vty.refresh speeds
up my test (though adds latency).
The bottleneck is Yi.UI.Vty.prepareAction, taking 40% inherited time and
alloc. And
that 40% is much worse than it sounds because it's critical; removing it
speeds up
pasting by ten times.
