Comment:

 Overall, very well done given the rather informal requirements.

 A few questions:

 1. Should there by any prerequisite statements to determine what if any
 other load
 exists on either machine and/or network?  Would it be helpful to have
 gathered some
 basic network metrics, ping time etc?

 2. Should Test Procedure include statements indicating a required level of
 isolation
 or to ensure that there is no other traffic against the bind10 or its
 components.
 For example, on the DHCP test lab,  the windows boxes apparently are
 always trolling
 DHCP4 through out the lab. This introduces spurious traffic.

 Pertaining to the output collected.  It would be perhaps, helpful to have
 the
 charts together on a single sheet, maybe stacked vertically. Also the
 legend does
 not specify units of measure for time.

 Minor comment on dhcp-val/doc/performance-test-setup.txt:

     In the paragraph, near the end of document:

     " The server system should already have all prerequsities needed to
 build BIND10 installed.
     In case any of them is missing for any reason, please refer to BIND10
 System Specific Notes
     for the BIND10 setup on the FreeBSD:
 http://bind10.isc.org/wiki/SystemNotesFreeBSD"

     I believe you should replace "server" with "client" or "perf-s1.lab".

 An observation:

 It is interesting that regardless of the backend employed and the ex rate,
 the average delay
 time is essentially the same until you hit a level that overwhelms the
 system and the drop rate
 gets large.  In other words, the minimum response time doesn't really
 change until you break the
 system.
