WebBench Configuration

Items in blue were modified from the standard WebBench 2.0 zd_static_v20.tst test. This is a 100% static workload that uses HTTP 1.0 without keepalives.

WebBench Test Suite Configuration Parameters

Parameter	Value	Comment
Ramp Up	30 seconds	This is the amount of time at the beginning of a test mix during which WebBench ignores any file operations that occur.
Ramp Down	30 seconds	This is the amount of time at the end of a test mix during which WebBench ignores any file operations that occur.
Length	300 seconds	The total time for which WebBench will run a test. It includes both the Ramp Up and Ramp Down times.
Delay	0 seconds	How long a test system is to wait before starting a test after it is told by the controller to start. Each test system will pick a random number less than or equal to this value to stagger the start times of all test systems.
Think Time	0 seconds	How long each test system will wait before performing the next piece of work.
Number of Threads	2	The number of worker threads used on each test system to make requests to a Web server. The total number of threads in a mix is the number of threads times the number of clients in that mix.
Receive Buffer	4096 bytes	The size of the buffer WebBench uses to receive data sent from a Web server.
% HTTP 1.0 Requests	100 %	The percentage of HTTP requests that are made according to the HTTP 1.0 protocol. WebBench does not support keepalives for HTTP 1.0.
Number of Mixes	16	Each mix tests the server with a different number of test systems. Mix 1 uses 1 system, Mix 2 uses 8 systems, and subsequent mixes increment the number of test systems by 8.
Number of Clients	120	The maximum number of test systems available to be used by any test mix. The actual number of test systems that participate in a mix depends on the number specified in the mix definition and whether an error occurred to take a test system out of a particular mix.
