- Correct. I am saying that nodejs is slower in general. The reason you would use nodejs is to save development time, and not to extract the last drop of performance. It is for the same reason that people have written so many apps on Python and Ruby.

- I/O in nodejs is always asynchronous. I/O in typical .Net apps is almost always synchronous, due to programmer choice. This approach is followed in the vast majority of Asp.Net apps. So according to you, this would imply that most .Net programmers don't know how to program in .Net.

- I can't follow how "ORM magic" is related to I/O. The ORM magic I remember has been a terrible experience for me when I had to use .Net (3-4 years back). We have to write our own ORM to replace EF, since it was dog slow. Including the LINQ expression tree parser, design-time tools etc. You can find this result here: https://github.com/jeswin/AgileFx

I know that things finally got better after EF4. But I haven't worked much on .Net of late.

Nitpick: actually Node lets you do synchronous IO (http://nodejs.org/api/fs.html#fs_fs_readfilesync_filename_op...). Sometimes you can chose to use synchronous IO, for instance to do something in the initialization phase of your server.

Yeah I like the flexibility of nodejs and thats the reason I want to try it. It seems too cumbersome to setup an IIS website etc just to try some simple stuff.

As far as ORM go EF is kind of OK but its not really mature even at its current release. IMO NHibernate is the way to go, and boy its a good way... There are also others that are even faster than NHibernate but its the most fully featured and easily extensible so I just love it
