fhb (Faban HTTP Bench) user - You do not have a predefined benchmark but want to create simple to moderately complex http tests. The fhb tool provides a simple command line interface to generate load and measure throughput and response times against arbitrary web sites. Moderately complex workloads can be defined in a workload configuration file and passed to fhb at invocation.

As a special case, fhb (Faban HTTP Bench) does not support multiple driver agents. It also does not make use of the Faban master process for the web user interface. In contrast, fhb drives the load from a sinigle system and uses the command line interface for invocation. It also cannot control server processes on the SUT or collect any statistics for that matter. Faban is constrained to only one system acting as both the master and the driver agent.
？？？？
意思是 driver 和 agent 必须在一起？

Run '. /sw/bin/init.sh' to set up this terminal session environment to useFink. To make the software installed by Fink available in all of your futureterminal shells, add '. /sw/bin/init.sh' to the init script '.profile' or'.bash_profile' in your home directory. The program /sw/bin/pathsetup.sh canhelp with this. Enjoy.
