> FWIW I also did a test of Node:master and that performance was within 2% of what I measured for io.js.

It would have been a good thing to include that comment to the article as well.

I thought about that. But it would have diminished the point I was trying to make: Always test with different versions as performance may differ by a LOT.

Well, if the point is that they are different then I see what you're saying but in actual fact the point seems to be they're almost equal.

He was talking about differences between point versions. 0.10 has dramatically different performance to 0.11. io.js is using 0.11, as is node:master, but older node was using 0.10.

I.e. the difference isn't necessarily node vs io, it's one point release of V8 to the next as used by node and io.

Supremely bad title then.
