E5520 vs E7400?

[idata]

Hello, I have a question, we have a system that uses the JBOSS java version 4. the problem is not using more than 22% of our server processor. The server is a HPML350 G6 with 2 QuadCore processors (E5520), 36GB of RAM, SAS disks (only for Windows 2008 R2 Enterprise) and Netapp Storage(iSCSI) for vhd file. A Hyper-v virtual machine with JBOSS.

The same java process on a PC Core2Duo, E7400 processor, 3GB of Ram, and SATA drives without Hyper-v, runs 50% faster. Why can be?

The JBOSS is using a single Threat / core. It may be that the problem?

The performance of a system is not only dependent on the processor; from the processor side, what you may want to do is make sure it is being properly recognized and make sure it is properly working.

To make sure the processor is being properly recognized, there is the Intel® Processor Identification Utility: http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=7838 http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=7838

To verify the processor's functionality, you can run the Intel® Processor Diagnostic Tool: http://www.intel.com/support/processors/sb/CS-031726.htm http://www.intel.com/support/processors/sb/CS-031726.htm

If the processor is working properly then you will need to do some further research on the systems compared; furthermore, in case you see a recognition problem with the processor, proceed making sure the latest BIOS version of the system is loaded.
