They're all good engines. SpiderMonkey is definitely in some aspects while v8 is faster in others. JSC is probably faster in some other aspects. I doubt that iojs will switch away from v8 because of how tightly integrated it is until, and if, we break it into pieces ( #9 ) but that is off the table for now because it is a major rewrite and requires a lot of time that no one has currently. |
It would be, at present, prohibitively time-consuming to switch Node over to a different JavaScript engine -- though it could be approached as a separate project. For more background, there's a bunch of discussion over here. |

Just wondering if SpiderMoney has been given any review recently as a replacement to V8?

Other than from a pure performance perspective my thinking is Mozilla's is a better fit with io.js than other corporate entities.
