Hi guys, In addition: a. If you suspect that the server behaves differently when receiving requests from the same IP, you could double check this using the new feature in version 2.4, ip spoofing (available only for the Http Request Http Client sampler). Note that some network admins might not be ok with this practice and it is not recommended unless the test system is isolated from the rest of the work network.
b. When testing distributed (even with no server-client config), save the logs (as .csv) to the disk and then load them both, after the test, into a single & clean listener in order to properly compare with the previous results (for example, throughput is tricky unless you aggregate all results, from all jmeter servers instances). Hope this helps. On Mon, Dec 27, 2010 at 5:35 PM, Anthony Johnson <ans...@gmail.com> wrote: > Hello, > 100 threads is not an over-whelming amount of load from my > experience.
