Free does the taks benchmark cause stress software for linux

Easy Benchmarking Suite is aimed at testing and benchmarking sites. Basically, the suite can:
- Issue requests to a URL. A benchmark typically consists of a given number of clients that concurrently issue a number of requests. A request can be any HTTP request (GET, POST, HEAD etc.) with all necessary HTTP header information (session cookies, basic authentication information, etc.);
- Get a quick overview of the results of a benchmark: how many trials succeeded, what are the average times for connecting and processing, what is the standard deviation of these times;
- Prepare a GnuPlot command file so that the obtained results can be plotted.
This document describes the suite. Furthermore, manual pages are provided for the separate parts of the suite: sitebench, sitecollect, and siteplot.

The Open CORBA Benchmarking Suite measures several basic performance aspects of various CORBA brokers.
The suite produces an XML output that can be submitted to a searchable database of broker performance data and browsed in a graphical form. The suite is portable to a number of platforms and brokers.
For C++ brokers
Enter the "C++" directory. Then enter the subdirectory of that directory that corresponds to the broker of your choice. Check the README file there for further instructions, usually you will use "make" to compile the benchmark.
For Java brokers
Enter the "Java" and then the "build" directory. Then enter the subdirectory of that directory that corresponds to the broker of your choice. Check the README file there for further instructions, usually you will use "ant" to compile the benchmark "ant run" to execute the benchmark.
Understanding results
The results do not get printed until the benchmark is finished, which can take from 2 to 4 hours depending on the platform. The best way to view the results is to capture them to a file and view them graphically at http://nenya.ms.mff.cuni.cz/~bench.
Enhancements:
- Support for system information on Linux 2.6 kernels.
- Slight extensions to the documentation.
- Support for some recent brokers on Solaris (VisiBroker 6.0, omniORB 4.0.5, JacORB 2.2.1).
- Support for some recent brokers on Linux (omniORB 4.0.5, JacORB 2.2.1, JDK 1.5.0, TAO 1.4.3).

Apache Hello World Benchmarks is a benchmarking tool that seeks to give a sense of Web application execution speed on various software platforms running under the Apache Web server.

Benchmarks can vary greatly from system to system, so this tool allows one to get numbers on ones own platform. Applications tested include mod_perl, mod_php, Tomcat, and Apache::ASP, with over 62 benchmarks in all.

Benchmark Descriptions:

Hello World 2000 ( 2000 )

The 2000 benchmark tries to emulate a heavy web page template. It is typically 3K+ in program length that results in output of over 20K. While this does not properly reflect any web applications speed of back end business logic execution, it does show a template heavy request with some application logic and loops, some HTTP parameter passing, and much variable interpolation in the output stream.

Hello World ( hello )

The Hello World benchmark merely prints "Hello World" and as such is a good test for the fastest a web page could ever run under the given web application environment. For historical reasons, the benchmarks are written to print "Hello" and then add to the output World as a raw string.

HelloDB ( hellodb )

The HelloDB benchmark merely queries the database for the string "Hello World", and as such represents the fastest a web application can process a request when talking to a database. This is a new benchmark with only MySQL supported for now, but more environments and databases will be added over time.

XSLT Big ( xsltbig )

This benchmark hits an XSLT rendering engine hard with 18K+ XML being transformed with a 1K+ XSL stylesheet for over 20K output. Though XSLT is generally slow, many applications will use XSLT caching to speed up response times. This benchmark should emulate well a real world XSLT usage scenario, with perhaps the XSL itself being too trivial.

Hello XSLT ( xslt )

Like the Hello World benchmark, the XSLT version just outputs "Hello World", or the closest we can get when doing XSLT, so it too demonstrates the fastest an application can render a page with XSLT. Benchmarks should be similarly configured between xsltbig and xslt, so a slow caching layer that benefits the former might slow down this benchmark.

Benchmark is a Perl module with benchmark running times of Perl code.

SYNOPSIS

use Benchmark qw(:all) ;

timethis ($count, "code");

# Use Perl code in strings...
timethese($count, {
Name1 => ...code1...,
Name2 => ...code2...,
});

# ... or use subroutine references.
timethese($count, {
Name1 => sub { ...code1... },
Name2 => sub { ...code2... },
});

# cmpthese can be used both ways as well
cmpthese($count, {
Name1 => ...code1...,
Name2 => ...code2...,
});

cmpthese($count, {
Name1 => sub { ...code1... },
Name2 => sub { ...code2... },
});

# ...or in two stages
$results = timethese($count,
{
Name1 => sub { ...code1... },
Name2 => sub { ...code2... },
},
none
);
cmpthese( $results ) ;

$t = timeit($count, ...other code...)
print "$count loops of other code took:",timestr($t),"n";

$t = countit($time, ...other code...)
$count = $t->iters ;
print "$count loops of other code took:",timestr($t),"n";

# enable hires wallclock timing if possible
use Benchmark :hireswallclock;

The Benchmark module encapsulates a number of routines to help you figure out how long it takes to execute some code.

timethis - run a chunk of code several times
timethese - run several chunks of code several times
cmpthese - print results of timethese as a comparison chart
timeit - run a chunk of code and see how long it goes
countit - see how many times a chunk of code runs in a given time

dkftpbench application is an FTP benchmark program inspired by SPECweb99. The result of the benchmark is a number-of-simultaneous-users rating; after running the benchmark properly, you have a good idea how many simultaneous dialup clients a server can support. The target bandwidth per client is set at 28.8 kilobits/second to model dialup users; this is important for servers on the real Internet, which often serve thousands of clients on only 10 MBits/sec of bandwidth.
The final result of the benchmark is "the number of simultaneous 28.8 kilobits/second dialup users". To estimate this number, the benchmark starts up a new simulated user as soon as the last one has finished connecting. It stops increasing the number of users when one fails to connect, fails to maintain the desired bandwidth, or the limit specified by the -n option is reached. It runs the simulated users until the amount of time specified by the -t option has elapsed since the last simulated user birth or death; the final score is the number of users still alive at the end.
Main features:
- Compiles and runs on Linux, FreeBSD, and Solaris (or did, last I tried)
- fetches many files in parallel
- waits for each connect to finish (and then a bit) before starting next one; slows down to < 1 connect/second when it reaches 75% of desired number of users. This spreads out user activity more evenly.
- checks bandwidth continuously during each file fetch, stops adding users if any fetch too slow
- throttles each fetch to use only the specified bandwidth
- search for the max number of supported users
- Displays verbose error message when any user fails
- Aborts if it detects the client system running out of resources
- Aborts if connecting to the server takes > 5 seconds
- Aborts if it takes longer than 5 seconds to get first packet of a file
- Uses new Poller class for scalability; you can specify which Poller to use on the commandline
- Supports slow datarates (before, it only handles rates above 80kbits/sec on some systems)
- Lets you set how picky it is about datarates (before, its must be faster than threshold was fixed at 3/4 the target bandwidth)
- Supports alternative readiness notification methods like O_ASYNC and O_ONESIGFD
- Provided both as a standalone executable, and as a Corba object. (Thanks to http://corbaconf.kiev.ua/ for the Corba autoconf macros.
- Switches to BINARY mode after login. (The client API lets you choose; edit robouser.cc to skip the START_TYPE state if you want to use ASCII.)
Example:
After unpacking the sources, configure them for your system with the command
./configure
This will generate Makefile from Makefile.in.
To make sure the sources arrived intact and work properly on your system, type
make check
It will build all unit tests, and fail if any unit test fails. You must be connected to the Internet, as this will try to download a file from ftp.uu.net.
To build the system tuning tool dklimits, type
make dklimits
Run it on both the client and the server machine; make sure that the number of files it can open is about three times the desired number of users, and that the number of ports it can bind is higher than the desired number of users. You should not be running X Windows or any other programs on the client and server machines when running the benchmark.
To build the benchmark, type
make
This produces the executable dkftpbench, the tuning program dklimits, and a bunch of unit tests (executables with names ending in _test) that you can ignore for now.
Heres a simple use of dkftpbench:
./dkftpbench -n1 -hftp.uu.net -t15 -v
This tells bench to simulate one user fetching the default file from ftp.uu.net repeatedly, and stop after fifteen seconds. The program produces this output:
Option values:
-hftp.uu.net host name of ftp server
-P21 port number of ftp server
-n1 number of users
-t15 length of run (in seconds)
-b3600 desired bandwidth (in bytes per second)
-uanonymous user name
-probouser@ user password
-fusenet/rec.juggling/juggling.FAQ.Z file to fetch
-m1500 bytes per packet
-v1 verbosity
1 users
User0: fetching 22708 bytes took 6.530000 seconds, 3477 bytes per second
User0: fetching 22708 bytes took 6.530000 seconds, 3477 bytes per second
Test over. 1 users left standing.

UMark project is a free graphical user interface that allows gamers and hardware reviewers to easily configure and run benchmarks on Unreal Tournament 200x (UT2004 and UT2003, both demo and retail versions).
Benchmarking with UMark is very flexible, as it can run totally customizable benchmarks. At the same time, it also offers standard benchmarking which imitates the official UT200x benchmark batch file tests.
UMark supports three types of UT200x benchmarking: "botmatch","flyby", and "timedemo" benchmarks. Each benchmark type has its own upsides and downsides.
Timedemo
Timedemos are pre-recorded matches that can be played back as fast as your computer can render it. While timedemos have the consistency of flybys and the gameplay accuracy above that of botmatches, there are no official demo recordings, therefore they are non-standard.
Flyby
Although flybys are standard and more consistent by always following the same paths, not all maps support them and they dont include the abundance of animated sprites or process the game rules that you would find in playing a typical match of UT200x.
Botmatch
Botmatch benchmarks include the things that make up an actual UT200x match, and have close framerates to a "real" game of UT200x, yet they function primarily on AI, which may cause the benchmarks themselves to be inconsistent when using different options.
UMark specializes in botmatch bencharking because botmatches are widely supported and have the most response to UMarks flexible configurations.
UMark also provides an engine for gathering results for saving and loading at another time, or to submit into an online score database (UMark Online) where users can search and compare results with other users based on a number of factors.
Results are displayed in numbers and bar graphs, along with hardware information. UMark Online members may post links to their scores so they can be viewed publicly by their peers.
Enhancements:
- Latest source snapshot, with features unseen in version 1.0 Beta 3, including built in HTML graph results browser (embedding Mozilla if installed).
