Hello all, I've looked through Daytrader workload results and analysis for Geronimo published at http://www-1.ibm.com/support/docview.wss?uid=swg27006724 For the bar diagrams, which show Geronimo and 'target' server indicators, immediate questions are: - what is the measure unit for values in Y-axis?
The Y-Axis represents transactions per second.
- how are the values for 'target' performance received?
One problem with performance measurments is that they typically incite many people to claim victory or cry foul depending on the results. This is also complicated by the fact that many commercial products have a no benchmark publish clause in their licenses. In order to have something to compare Geronimo to as well as avoid the inevitable fallout of naming a comparison point I did a series of measurments on other Open Source and commercial AppServer products. I thook these results and created the competitive target metric.
The competitive target metric is simply my estimation of a respectable performance measurement. Meaning, as we achieve that metric one should be happy with the results.
Note that these numbers are pretty old. I have a new set of data that I've been saying will be out for a while. I guess its time to actually make that happen. So, for purposes of consumption I would wait a few days for the new report to surface. We'll post it on our site.
Also, could someone clarify if the performance data was collected on a client or a server side?
All the TPS metrics were gathered from the client. The goal was to get the server to 100% CPU utilization.
Also, if you guys are willing we could use some of the newer Potomac 3.6Ghz chips :)
Thank you in advance for the answer. -- Best regards, Maxim Berkultsev, Intel Middleware Products Division
