This document describes the use of +queryperf for authoritative server performance testing. + + +Building + +To build queryperf, just do + + sh configure + make + + +The test environment + +It is recommended that you run queryperf and the name server under +test on separate machines, so that the CPU usage of queryperf itself +does not slow down the name server. The two machines should be +connected with a fast network, preferably a dedicated 100baseT +segment. Testing through a router or firewall is not advisable. + + +Configuring the server + +The name server under test should be set up as an authoritative +server, serving one or more zones similar in size and number to +what the server is expected to serve in production. + +Be sure to turn off recursion in the server's configuration +(in BIND 8/9, specify "recursion no;" in the options block). +In BIND 8, you should also specify "fetch-glue no;"; otherwise +the server may attempt to retrieve glue information from the +Internet during the test, slowing it down by an unpredictable +factor. + + +Constructing the input file + +You need to construct a queryperf input file containing a large and +realistic set of queries, on the order of ten thousand to a million. +The input file contains one line per query, consisting of a domain +name and an RR type name separated by a space. The class of the +query is implicitly IN. + +When measuring the performance serving non-terminal zones such as the +root zone or TLDs, note that such servers spend most of their time +providing referral responses, not authoritative answers. Therefore, a +realistic input file might consist mostly of queries for type A for +names *below*, not at, the delegations present in the zone. For +example, when testing the performance of a server configured to be +authoritative for the top-level domain "fi.", which contains +delegations for domains like "helsinki.fi" and "turku.fi", the input +file could contain lines like + + www.turku.fi A + www.helsinki.fi A + +where the "www" prefix ensures that the server will respond with a +referral. Ideally, a realistic proportion of queries for nonexistent +domains should be mixed in with those for existing ones, and the lines +of the input file should be in a random order. + + +Running the tests + +Queryperf is run specifying the input file using the "-d" option, as +in + + queryperf -d input_file -s server + +The output of queryperf is mostly self-explanatory. Pay attention to +the number of dropped packets reported - when running the test over a +local Ethernet connection, it should be zero. If one or more packets +has been dropped, there may be a problem with the network connection. +In that case, the results should be considered suspect and the test +repeated. diff --git a/contrib/queryperf/config.h.in b/contrib/queryperf/config.h.in new file mode 100644 index 0000000..744afdd --- /dev/null +++ b/contrib/queryperf/config.h.in @@ -0,0 +1,37 @@ +/* config.h.in.
