Taken from the dbench README file:
Netbench is a terrible benchmark, but it's an "industry
standard" and it's what is used in the press to rate windows
fileservers like Samba and WindowsNT.
In order for the development methodologies of the open source
community to work we need to be able to run this benchmark in
an environment that a bunch of us have access to. We need the
source to the benchmark so we can see what it does. We need
to be able to split it into pieces to look for individual
bottlenecks. In short, we need to open up netbench to the
masses.
To do this I have written three tools, dbench, tbench and
smbtorture. All three read a load description file called
client.txt that was derived from a network sniffer dump of a
real netbench run. client.txt is about 4MB and describes the
90 thousand operations that a netbench client does in a
typical netbench run. They parse client.txt and use it to
produce the same load without having to buy a huge lab. They
can simulate any number of simultaneous clients.
Improve macros and add prototypes.
Improve resolution of get_resolution().
Changes to support RedHat 9.0.
Special handling of NAME for broken frontend in Cygwin/Windows env.
Add support for the CrayX1
Remove reference to PAGE_SIZE for linux. This causes problems
with SuSe 8.
Fixup for SCO build.
Add -DHAVE_PREAD for Solaris8-64 target.
Code cleanup for Linux
Improve -+d so that each byte is more unique.
Improve byte level validation.
Provide byte level error detection with Found char and Expecting Char in
-+d mode.
Improve speed of -+d without losing uniqueness of bytes.
Fix so that Windows can use multiple processes. Needed mmap like SCO.
Use malloc() instead of mmap() for threads memory, instead of mmap.
Make CPU utilization use doubles everywhere.
Add support for CPU utilization while in distributed mode.
Make all times relative so multi node can do CPU usage.
Remove unused variables.
Zero compute_val inside of loops.
Add support for O_DIRECT for IRIX and IRIX64
Improve macros and add prototypes.
Improve resolution of get_resolution().
as benchmarks/nettest (originally in net).
The nettest and nettestd commands perform client and server
performance tests for various types of interprocess communication.
These tests time the data throughput of pipes and UNIX domain, TCP,
and UDP socket connections.

The SKaMPI-Benchmark is a suite of tests designed to measure the performance
of MPI. MPI (Message Passing Interface) is a machine independent standard to
provide an efficient interface to message passing libraries of different
parallel machines. The goal of SKaMPI is to create a database to illustrate
the performance of these different MPI implementations. This database should
allow to:
1. Decide how to implement portable and efficient MPI programs.
2. Predict the performance of MPI programs.
3. Describe supercomputers in terms of MPI.
and portability stuff:
Added -z option. This is to be used with the -a option. It
provides more complete testing for small record sizes
when the file sizes are very large.
Added -y and -q to set record size range
Added command line to output
Put auto cross over back to 16 Meg
Add labels to the latency/offset output files.
Prevent mixed modes. Auto and throughput.
Added support for the Plus extended options.
Added support for -+u option. Cpu utilization.
Added network testing mode. -+m (Experimental) Tested: Linux, HP-UX
Added -xflag support for distributed mode.
Handle interrupts when in distributed mode.
Disable CPU utilization in distributed mode.
Add -+m cluster option to the help list and the list of options.
Enable more options in Cluster mode.
Add protocol version checking for distributed messages.
Add -+d file I/O diagnostic mode.
Fix some compiler warnings and implement the -+x option for
setting the multiplier used for file and record size incrementing.
Reduce the message traffic due to master's distribution of STOP. Only
one STOP distribution is needed. More can lead to socket buffer overflows.
Add -+p percentage read option.
Improve the mixed mode distribution algorithm.
Introduce -+r for O_RSYNC.
Add speed check code.
Increase maximum threads/procs to 256
Add contribs and -+t to help splash screen.
Disable fread and fwrite testing if mmap or async is in use.
Add pread/pwrite throughput testing
Permit smaller values for -n and -g
Make initial write in initfile() a page size request.
Stop test if file can not be written.
bonnie++ (1.03a) unstable; urgency=low
* Fixed the bugs in GCC 3.2 compilation and compiled with GCC 3.2. Results
will be slightly lower now, but it's still a fair test of compiler/OS...
bonnie++ (1.03) unstable; urgency=low
* Fixed a bug in error handling during a stat test with multiple directories.
bonnie++ (1.02d) unstable; urgency=low
* Fixed a bug where it would SEGV if you specified more than 999 directories
(now it handles 99,999 and displays an error message if you ask for more).
Closes: #171507
* Made it build on Irix.
* Fixed <vector> and <algo> checks to work with GCC 3.2.
have it be automatically included by bsd.pkg.mk if USE_PKGINSTALL is set
to "YES". This enforces the requirement that bsd.pkg.install.mk be
included at the end of a package Makefile. Idea suggested by Julio M.
Merino Vidal <jmmv at menta.net>.
moving the state directory for bytebench to /var/benchmarks instead of
trying to keep state in ${PREFIX}/share/bytebench. Distribution changes
from version 3.6 include:
* Double precision Whetstone instead of the old "double" benchmark.
* Removal of some obsolete files.
* "system" suite adds shell8.
* perlbench and poll added as "exhibition" (non-index) benchmarks.
* Minor change to fstime.c to fix overflow problems on fast machines.
* A lot more operating system-oriented tests into the index.
* Many tests rewritten to be more relevant for modern processors.
* New baseline: SPARCstation 20-61 with 128 MB RAM, a SPARC Storage
Array, and Solaris 2.3
pkgsrc. Instead, a new variable PKGREVISION is invented that can get
bumped independent of DISTNAME and PKGNAME.
Example #1:
DISTNAME= foo-X.Y
PKGREVISION= Z
=> PKGNAME= foo-X.YnbZ
Example #2:
DISTNAME= barthing-X.Y
PKGNAME= bar-X.Y
PKGREVISION= Z
=> PKGNAME= bar=X.YnbZ (!)
On subsequent changes, only PKGREVISION needs to be bumped, no more risk
of getting DISTNAME changed accidentally.
better benchmark without being too unreasonable on the disk requirements.
Changelog:
1.14 - Automatically stop run if work files are depleted
1.5 - It was pointed out by many (most recently Michael Flaster) that the
pseudo-random number generator was more pseudo than random. After
a review of the literature and extensive benchmarking, I've replaced
the previous PRNG with the Mersenne Twister. While an excellent PRNG,
it retains much of the performance of the previous implementation.

Also changed MB definition to 1024KB, tweaked show command
http://www.iozone.org/src/current/Changes.txt
I have patched the source however, to allow use of the pread/prwite
tests, via the -E extension mode. Also, the benchmark target has been fixed.

first component is now a package name+version/pattern, no more
executable/patchname/whatnot.
While there, introduce BUILD_USES_MSGFMT as shorthand to pull in
devel/gettext unless /usr/bin/msgfmt exists (i.e. on post-1.5 -current).

doesn't enable any functionality. It is here as a marker, so people building
binary packages know that these packages have version-specific features
that would make them incompatible with other point releases.. (such as
LKM's)
pages that are installed will be gzip-compressed, if MANZ is set, or
not if MANZ is not set. If the package uses bsd-style .mk files, the
variable MANCOMPRESSED_IF_MANZ should be set to a value of "yes" in
the package Makefile. This replaces the previous method of specific
inclusion of bsd.prefs.mk, followed by a check for MANZ and
conditional assignment of MANCOMPRESSED.
Add appropriate documentation, and change all necessary ocurrences in
package Makefiles.
In the vast majority of cases, nothing has changed (i.e. .tgz, .tar.gz,
and .tar.bz2).
EXTRACT_USING_PAX can be set as before.
For custom extractions, instead of using EXTRACT_BEFORE_ARGS,
EXTRACT_AFTER_ARGS and EXTRACT_CMD, simply set EXTRACT_CMD to be the
command needed to decompress and extract the lements from the archive.
${DOWNLOADED_DISTFILE} can be used to reference the distfile(s).
e.g. for compressed shars, where previously there was:
EXTRACT_CMD= ${GZCAT}
EXTRACT_BEFORE_ARGS=
EXTRACT_AFTER_ARGS= |sh
now use:
EXTRACT_CMD= ${GZCAT} ${DOWNLOADED_DISTFILE} | ${SH}
package uninstalled, with the exceptionof lmbench. Make non-batch
targets for all the benchmarks, and create a results target which
places all the results in /tmp for easier collection.
- New, optional Makefile variable HOMEPAGE, specifies a URL for
the home page of the software if it has one.
- The value of HOMEPAGE is used to add a link from the
README.html files.
- pkglint updated to know about it. The "correct" location for
HOMEPAGE in the Makefile is after MAINTAINER, in that same
section.
