RFC 1564                      DSA Metrics                   January 1994


   79. Modify RDN

      (a)  10 siblings

      (b)  1000 siblings

10.1.8  Query rate

   As the time taken for a single read will usually be negligible, the
   following list and set of reads should give a clearer indication of
   the query rate.

   80. A list to return 100 entries for persons, and then a read of each
       entry returning all attribute values.

10.2  The results

   The results of the tests just described should be entered in Table 2
   (and optionally Table 3), at the end of the document.

10.3  Environment used for benchmarking

   Date of test.........................................................
   Name of tester ......................................................
   The results will be directly correlated to the test set-up used, and
   in particular, the hardware.  Please answer the following questions
   to describe the test environment:

      (a)  Processor (make and model) ..................................

      (b)  Processor speed (MIPS) ......................................

      (c)  Primary memory available ....................................

      (d)  If disk-based DSA, disk I/O interface and disk speed ........

      (e)  O/S version .................................................

      (f)  Network type and bandwidth (e.g., 10 Mbit Ethernet) .........

      (g)  Protocols in transport layer and below (e.g., TP 0, RFC1006,
           TCP/IP) .....................................................

      (h)  How/where timings obtained?

            o  C procedural interface ..................................

            o  DUA shell (e.g., Quipu's DISH) ..........................
