Im not sold on node. Why should i ristrict myself? There are async librarys in lots of languages you can use them if you have a problem that suits the async modle but you can use other models to if they are better.

The other thing with node is that it is single threaded do do multicore you have to use process witch are slow in communicating. This could work now because we often only use quadcores but in the next years we will have many many more. Is it a solution to start node up for say 16, 80 or 1000 cores?

Im not ranting on node I hear it works fine for some stuff but the benchmarks that got everybody so exited in the beginning was not really that practical.

If I write a low level it might be fast because it maps to the C stuff good but if I write a big application with lots of layers of JS will it still be fast? (I know that V8 is getting better but it there jet for big server applications?).

Hope somebody can talks about this.
