How to compare application performance on Linux vs Windows 2008?

5 pts.
Application performance
Oracle Application Server
WebLogic Server
We are testing a custom Oracle application (Weblogic 11G) on both a Suse Linux 10 server and a Windows 2008 R2 server. Both will be hosted on an HP DL380 G7 with quad processors and 64 GB RAM.

We are limited to free and built-in performance tools for each system. What factors/elements should we be comparing to determine which OS delivers the best performance for the application? I know that memory use and CPU use are two possible elements we can compare. I also found a reference that talks about monitoring the HEAP performance -though I am not totally sure what that is. Any suggestions of realistic elements that we can monitor and measure would be appreciated.

The application performance will be a factor in whether we select Linux as our application server host or continue to use the next version of Windows, since the old application "worked just fine on Windows 2003."

Software/Hardware used:
,H Proliant DL380 G7 server/64-bit; SuseLinux10; W2K8R2, Oracle 11g Weblogic

    When u compare Linux OS to Windows, consider factors such as cost of ownership, security and virtualization other than application performance. Novell provides the lowest cost, highest value operating system in the industry. There is no license cost for SUSE Linux Enterprise Server. The cost of a basic product subscription, which includes maintenance updates and product enhancements. There are no extra cost for client access to services running on SUSE Linux Enterprise Server. Every Windows vs. Linux server comparison has to include the essential factor of security. SUSE provides enterprise security at no extra cost, through AppArmor application level security technology. It gives network application security via mandatory access control for programs, protecting against the exploitation of software flaws and compromised systems. It is certified to be compliant with the CC - CAPP Where the list price of a Windows Server 2008 Enterprise Edition is too high which includes 25 Client Access Licenses (CALs). Windows 2008 CAL is required for each user or device that accesses or uses the server software. Remember, existing Windows 2003 CALs cannot be used with Windows 2008. Software Assurance, which includes product enhancements and a small amount of technical support, costs 25 percent of the total license fees for Windows Server and Windows Server CALs, and is charged annually. Windows OS have a long history of security flaws, many built into IE, IIS, ActiveX, and other components. These flaws have resulted in billions of dollars in lost business due to downtime required for patching, installing, security service packs and taking other measures. Though it is known that, in Linux Os, more manpower may require than Windows OS. There r more command line utilities than Windows and of-course it lacks of GUI features than Windows OS. As u told, this apps runs well in Windows 2003, it is recommended that, better go for Windows 2008, if the costs do not matter. U have not mentioned here, which SP u used here, cause, the latest version is SuSE Linux Enterprise Server 11 SP1. U can use this and gain more extra facilities than 10. At least u may try 10.4
