we are also missing patterns you are testing. Do you test entirely random
domain name every time or you are repeating same queries (real question is
whether resolver cache is used or not). Also what is your upstream link
connectivity? Your bandwith may also affect results.

> My server is:

> 4Gb Ram
> LSI Logic 1020/1030 Ultra320 SCSI Adapter
> Debian Etch
> 30Mb full internet access (!)
> i setup only one forwarder (dns of biggest ISP in italy) and i used dnsperf

> bind
>  Queries per second:   181.861585 qps
> in this case unbound is 20% faster.
