Hi Maxim,

Is it the time for me to move to FreeBSD?

The question isn't iowait, but how well your server behaves, i.e. 
how many requests it can serve.  You may want to monitor 
throughput and latency instead.

On the other hand, under linux using aio may be bad idea if your 
disk cache isn't completely trashed and still able to cache 
something as aio on linux requires directio.
