Python has a python/c barrier yes, but python's runtime is better equipped to handle crossing the boundary with low overhead because it was written with that use case in mind. v8, on the other hand, is optimized for running javascript code and so making the jump back and forth is considerably more effort for the vm.
I'm sure someone with more experience with node C bindings (or python C bindings for that matter) could give a more technical explanation. I'm more of an end-user and not as much a developer when it comes to such bindings. To further elaborate: You *can* do basic math in javascript just fine, and at a reasonable rate. For heavy lifting though, ya gotta go lapack/atlas/etc. --Josh On Tue, Jun 12, 2012 at 2:18 PM, Matt <hel...@gmail.com> wrote: > On Tue, Jun 12, 2012 at 3:29 PM, Joshua Holbrook <josh.holbr...@gmail.com> > wrote: >> >> To elaborate on the math aspect: Because of the significant js/C >> barrier and the need for optimized code, node is a poor choice for >> significant computation.
