Comment #2 on issue 2131 by [email protected]: Array.splice() slows
down at arrays larger than 114467
http://code.google.com/p/v8/issues/detail?id=2131
I strongly suspect that this is due to the backing store of the larger
array being allocated in large-object space, where we currently cannot do
efficient trimming of arrays from the left. So we end up moving the whole
content to the left and adding the slots to the store-buffer because the
backing store is not in new-space. This is especially brain-dead in this
case, where we actually do not move anything at all, because 'start' is set
to zero. I have some ideas how to improve Array.prototype.splice for these
cases.
