Nodejs for community site?

[Benj]

Hi i like node and use it for async io and i'm thinking to expand its usage to more traditional web site such as forum and other social things.

Potential problem is that due to its single thread per process... Any cpu bound task is blocking.
I would delegate heavier tasks to a queue.... But i don't want to delegate ALL the little cpu bound tasks to a queue. This would complexifiy code too much.

So this is a question for those node devs with some experience using node for sites that are not pure io bound.

Can i keep node validating for example form fields? It goes over all submitted user fields server side and check against validation fields. Is this even too much cpu bound for a medium traffic site? What is your experience?
Any example site?

This kind of CPU use is trivial, and is zero issue for web apps. You can loop through 10k entries in a form field in microseconds.

The things you might need to farm out to a queue are more traditionally CPU heavy computations, like large matrix calculations.

A typical example in our (ideal.com) application is matching candidates to jobs. It's a large scale CPU calculation across hundreds of thousands of database entries. We do it using a queue system because it takes a long time. But validating form entries isn't something you'd ever put in a queue.
