These two tests should have given the same results since the total number of threads is the same. When using 2 jmeter servers, I added the Rate together to get a total number of requests / second. This _seems_ logical since each jmeter server is telling me it can do X number of requests per second, but the 1x40 and 2x20 tests should then have the same Rate number. I also don't understand why the web server's CPU jumped from 38% -> 72% when going from 1x40 to 2x20. This would indicate twice the number of users/threads. Any thoughts? :-) Thanks, js. -- Jean-Sebastien Morisset, Sr. UNIX Administrator Personal Home Page JS & Melanie's Homebrewery Underwater and Travel Photographs --------------------------------------------------------------------- To unsubscribe, e-mail: jmeter-user-unsubscribe@jakarta.apache.org For additional commands, e-mail: jmeter-user-help@jakarta.apache.org
