Installing Apache JMeter

JMeter is distributed as a set of zip (or tar or tar-gz) archive files.

The files are called:

jakarta-jmeter-<version>_bin.zip - JMeter binaries
jakarta-jmeter-<version>_lib.zip - 3rd party jar files
jakarta-jmeter-<version>_src.zip - JMeter source
jakarta-jmeter-<version>_api.zip - JMeter Javadoc

Installing JMeter runtime:
Download the _bin and _lib files
Unpack the archives into the same directory structure

The other archives are not needed to run JMeter.
