Tomcat Performance on a Dual Processor Win2K Machine.
Hi All, I have a java application running under this setup: Tomcat-3.2, IIS-5.0,SQL Server-7.0 with Windows 2000 Professional on a Dual Processor Machine. The problem am encountering is High CPU utilization and non-release of CPU by the application. Any pointers to the cause of this problem. Btw running the same application on a Single processor doesn't cause the problem. Rgds, Karthik _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Could be something on your app or in the JVM you use. My dev setup is exactly as yours ( Dual processor ) , but i use Tomcat 3.3, i did not found that that problem with the apps i normally run on tomcat, btw JetSpeed, CoCoon2 and my own apps ( JDBC intensive which every DB in market ).

AW: Tomcat Performance on a Dual Processor Win2K Machine.
On machines with more than one processor, the possibilty that an implementation error with synchronized will have impact, drastically grows. So this might be the reason for this behaviour. There are tools out there that can detect such problems: (At least they promise to do so) http://www.numega.com/devcenter/jc.shtml (Commerzial) http://www.ispras.ru/~knizhnik/jlint/ReadMe.htm (Free) -Ursprüngliche Nachricht- Von: karthik g [mailto:[EMAIL PROTECTED]] Gesendet: Freitag, 18.

Are you sure your configuration is exactly the same? In the readme file, item 6.11 (I believe) mentions how a mis-configuraiton can cause infinite loops. If you changed your server.xml file, I would look at this.

Please read recent discussion about this, missing '/' context in server.xml can cause high cpu utilization problems venkat Hi All, I have a java application running under this setup: Tomcat-3.2, IIS-5.0,SQL Server-7.0 with Windows 2000 Professional on a Dual Processor Machine.
