Hi all, I'm using OFBiz to study the performance of web service in the cloud. I found a problem when I deploy OFBiz on a 2 core server, which has 4G memory. The OFBiz I used is the 12.04.03 version. The OS is ubuntu 12.04.
I was using OFBench to send requests to OFBiz. The OFBench is able to send different kinds of requests, like login, logout, visit main page. I was testing how many users I set in OFBench will saturate the server. At some point I found that the server was overloaded when I set 20 users because the mean response time for the "main" request is over 10 seconds. However, the CPU utilization is only 60%. I also did a test for one core server. When it's overloaded, the utilization is almost 100%. I was using the default derby database. I monitor the memory of the 2 core server, it was like 2GB used. So I guess memory is not a problem. The other parameters are default. This is not the first time I notice this problem. I also found this on other multi-core servers. Could anyone help me on this please? Thanks a lot in advance!!!! Best wishes, Weikun
