fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn ForteIn addition to various bug fixes, the following new capabilities

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Fortewere added in this release:

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -C option was added to resperf. This option enables the local

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte server to act as multiple clients. By default, the local server

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte acts as a single client.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - the -T option was added to dnsperf. This option separates the

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte number of clients from the number of threads and allows more

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte clients to be simulated effectively. Note that using this option

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte impacts CPU and memory, so we recommend limiting the number of

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte threads.

93c20f2609342fd05f6625f16dfcb9348e7977f2Sukumar SwaminathanIn the dnsperf command, the following changes occurred:

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

93c20f2609342fd05f6625f16dfcb9348e7977f2Sukumar Swaminathan - The socket buffer size is no longer set to 32 kilobytes by default.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - A new -c clients option was added to enable the server to act as

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte multiple clients. Each client uses the same source IP address with a

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte unique source port. Use the "clients" argument to specify the number of

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte clients represented by the server. We recommend limiting the number of

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte clients represented by the server because the dnsperf process uses two

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte threads for each client (one thread for sent packets and one for

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte received packets), which impacts CPU and memory.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - Example query files are no longer included with the dnsperf program.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - Latency reporting improved. When the -v (verbose mode) option is

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte configured with the dnsperf command, the command output now includes

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte latency measurements and the DNS RCODE of each response. This enables

e2ca2865a6870e9c6cbef6becbcc68cafde64537Sukumar Swaminathan users to create their own latency graphs.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - Performance was enhanced on modern operating systems so that faster

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte name servers can be tested.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The dnsperf command output is enhanced to display more information in a

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte compact format.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn ForteThe following options were removed from the dnsperf command:

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -A option for displaying command line arguments passed to the

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte dnsperf tool in the final statistics output. Now, the dnsperf command

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte output always displays command line arguments.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -T option for printing a histogram showing response latency after

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte completing a test run. Now, the -v option enables users to include

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte latency measurements in the dnsperf command output.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -H option for configuring the number of buckets for which response

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte latency is displayed. Now, the -v option enables users to include

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte latency measurements in the dnsperf command output.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -1 option for configuring the dnsperf tool to run through the input

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte file exactly one time. (Now, you use the -n 1 option to configure the

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte dnsperf tool to run through the input file one time.)

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -c option for including the number of responses received (for

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte each DNS RCODE) in the final statistics output. Now, DNS RCODE responses

93c20f2609342fd05f6625f16dfcb9348e7977f2Sukumar Swaminathan are always reported.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn ForteIn the resperf command, the following changes occurred:

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The socket buffer size is no longer set to 32 kilobytes by default.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte - The -A option, which displayed command line arguments passed to the

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte resperf tool in the final statistics output, was removed. Now, the

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Forte resperf command output always displays command line arguments.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn ForteThis release makes binary builds of dnsperf available in addition to

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn Fortethe source code version previously released.

fcf3ce441efd61da9bb2884968af01cb7c1452ccJohn ForteThis release of dnsperf includes a sample query file containing

100,000 queries to help with performance testing. This query file is

useful for checking latencies or a continuous dnsperf run. In the

binary distribution, this file is found at:

/usr/local/nom/examples/dnsperf/queryfile-example-100thousand

In the source distribution, it is at:

./examples/queryfile-example-100thousand

where "." is the directory made by extracting the source tarball.

Nominum recommends using a query file with at least 3 million queries

for a full resperf run as described in the man page; we make such a

file available for download at:

The following fix is included in the source distribution:

- 20996: makefile.in does not allow overriding mandir

The --mandir argument to configure, which allows the user to

specify the location man pages are installed, was incorrectly

ignored.

"queryparse" is a contributed program available in the source

distribution of dnsperf. It can be found at contrib/queryparse/.

The following changes were made to that program:

- 19717: contrib/queryparse includes outgoing queries

The queryparse script had no way of distinguishing between incoming

queries and outgoing queries when applied to a traffic trace from a

caching server. This was addressed by adding a new flag (-r) that,

when included in the command line, will keep queries with

RD=0. Otherwise, it will default to discarding them.

- The ability to parse responses instead of queries was added.

- A check was added to avoid short packets.

- Logic was added to detect link type and correctly set the initial

offset to handle both Ethernet and Cisco HDLC frames.

- Queryparse now uses pcapy instead of the btk python libcap module.

Note that announcements of new releases of dnsperf are sent to the

mailing list: dnsperf-announce@nominum.com. To be added to the

mailing list, send a message to dnsperf-announce-request@nominum.com

Nominum dnsperf 1.0.0.1

December 21, 2006

This release addresses the following issue in the dnsperf program:

- 18838/18782: dnsperf slow down issue

Because of an error in how timeout checking was being done, queries

were rarely timing out, so the number of valid queries in flight kept

dropping. This error has been corrected.
