this is just a benchmark kind of stress test with authoritative records, query 
logging has been disabled.

Logging. If query log is enabled it has significant impact on the performance. 
If syslog is used for the purpose it is even worse.

It is not clear what tests exactly do you perform. Is named serving 
authoritative data? If yes - enable the acache (disabled by default). If it is 
used as recursive server and it needs to query external servers this can be a 
factor too.
