Firstly, I would like thanks Martin and Prasanna for the msgs.
I would like to understand the concurrency and rate models implemented in the httperf tool. In some experiments I need to define a specific --rate to work in a constant concurrency level.
For example, I have an apache web server prepared to support until 200 concurrent conns (MaxClients 200). I want to create a load based on 200 persistent concurrent connections, where each connection will make 1000 requests (e.g. GET). The rate of the 200,000 GET requests is 50 reqs/s.
Q1: Is it possible ?
Trying to do that I'm handling the httperf's arguments and I found that setting the --rate=400 I get the follow msg "... <=200 concurrent connections".
Q2: What the symbol (<=) exactly means ?
Anyway, using the --rate value to reach a specific concurrent level isn't adequate in this case because I need to use another rate like a said based on 50 reqs/s.
Any information will be valuable.
