We've been able to squeeze 50000 qps out of a pipe backend. On a philosophical note, pipes are likely to be faster than TCP/IP, and SQL marshalling/unmarshaling is not free either.

People associate 'text based' with slow, but most SQL protocols are just as parsed, or even more so.

The pipe backend does have a performance bottleneck in 3.2 if you specify a timeout, see http://wiki.powerdns.com/trac/ticket/661
