Thanks! That's true. Incidentally, we spot tested the Vert.x test with a plain array in lieu of the CopyOnArrayList and there was no perceptible performance change.
We're very happy to make it more correct and eek out whatever small gains can be had--plus make the code cleaner. But if there are readers looking to improve the Vert.x numbers, I think we're going to need contributions from someone with a deeper understanding of Vert.x tuning (or some more time to invest in becoming that!)
