This is a basic but yet very powerful way to stress-test your site.

WordPress, Blogspot but also TYPO3 without HipHop and PHP7 (check out this benchmark) seem to be quiet good targets for this attack.

I basically managed to bring down my own blog with MySQL giving up 😀 and also slowed down Blogspot sites and managed to render a TYPO3-powered site basically defect. Shocking. Just imagine what an attacker could do running httperf like on 10x hacked servers. argh.

„Autobench is a Perl script designed to assist in the automation of benchmarking with httperf. It runs httperf a number of times against the target server, increasing the requested request rate each time, and produces output in the form of a CSV or TSV file which can be imported directly into a spreadsheet for further analysis or graphing.

Autobench also enables the easy comparison of two different web servers – it can test two servers and amalgamate the results in the same table, enabling comparative graphs to be drawn quickly and easily.

Obtaining autobench

Autobench can be obtained from

. Download the autobench tarball to your client machine, untar it, and run

make; make install

to install the autobench script.“

Description: Automates the benchmarking of web servers using httperf
autobench is used to to automate web server benchmarking. It runs
httperf against the specified host or hosts, ramping up the number of
requested connections, and logging the results in TSV or CSV format
files. Graphs can be automatically generated using gnuplot.

Description-en: An HTTP server performance tester
httperf is a tool to measure web server performance. It speaks the HTTP
protocol both in its HTTP/1.0 and HTTP/1.1 flavors and offers a variety of
workload generators. While running, it keeps track of a number of performance
metrics that are summarized in the form of statistics that are printed at
the end of a test run.
