...Can be used as a general-purpose Lua interpreter as well, simply replace #!/usr/bin/lua with #!/usr/bin/sysbench in your script. Execute events for this many seconds with statistics disabled before the actual benchmark run with statistics enabled. This is useful when you want to exclude the initial period of a benchmark run from statistics.

...Perftence can also be used without JUnit by using perftence-api distribution package. Full test results are provided in html, which can published directly with different CI's (e.g. Jenkins/Hudson). Runtime test statistics are also provided through logging (e.g. using slf4j-log4j and log4j). Pertence tool can also be used for finding out threading issues. Just write a test that uses the component you need to test for threading issues and assign load of threads to the test. Thanks to my employer (Nokia) for letting me publish the initial version of this tool as open-source!

Reads a PostgreSQL database log file, extracts the SQL statements and executes them in the same order and timing against another database server. Useful for performance tests with real-world workload.

The alio library can be dynamically pre-linked to existing executables and replaces file IO (i.e. calls to glibc's IO functions). This allows to gather statistics about IO, create IO trace files, or even implement a different IO behaviour (e.g. use separate IO servers to handle IO).

AwkStatistics is a script which is used to generate statistical data for csv data by using awk. It takes two columns from the input file, one is used to identify the row(option -i) and the other one is the column where the values are taken from (option -v). The script was designed for performance engineers to be able to analyze CSV-Data on the fly and have a good possibility to automate the analysis process.

RegressionSuite is a software test suite that incorporates measurement of the startup lag, measurement of accurate execution times, generating execution statistics, customized input distributions, and processable regression specific details as part of the regular unit tests. Essentially, RegressionSuite provides the frame-work around which the individual unit regressors are invoked (and details and statistics collected). Unit regressors are grouped into named regressor sets (or modules), and regressors are created by implementing specific regressor interfaces. ...

...This makes it difficult to analyze since every counter data is dumped into the log file. SarBox helps to analyze this log file and present data in graphical charts or text format. To collect sar statistics from an environment, use below syntax [user@host ~]# sar -A 30 2 > sar_linux.log “30 2” reports for every 30 seconds and total of 2 times, written in sar_linux.log.

Shadowtail is a Java/Spring framework for gathering numerical data (statistics) about a Java application. It is particularly useful as a source of data to feed Orca, the free tool for plotting textual data onto a directory on a Web server.
