This can, and will result in lost data.

I know... If there is a power failure things can happen. I'm know, but
the performance dif is really really big I just have to decide if I'm
willing to take that chance or not.

How much memory does this machine have and what version of postgresql
are you using?
It's only a test server with 512MB RAM, I only used it to see how well
would  the PostgreSQL do in a ugly case.

Given that optimal performance for postgresql can require up to 50% of available memory, you are going to leave the OS with 256MB of memory ?
