I kind of alluded to it in my reply, but I tend to agree- they spent a lot of time and hard work- looking in all the wrong places! Its hard to imagine how they missed the forest for the trees so badly here. Worse is- they never really explain where that 30x improvement came from- or if they even understand it themselves? They talk a lot about getting their memory issues under control, but hardly at all about actual parallelism- and it seems that even then they confuse it with merely speeding up operations that are blocking. I kind of expected this post to be "We did a whoops and had a blocking call to a DB/fs/compression call/whatever. This was all happening in the event loop and not being farmed out to the threadpool by libuv. We fixed it and now look like heroes to our CTO!"
