root and performance

[oiram]

Hello:

Useing jdk 1.3.1.08 I have seen that the performance of a multithreade application is increased a lot if the application run as root. If we make the same job with a monthread application the gain isn??t so much and in 1.4 the gain in a multithreaded application is imperceptible. The only significant effect is seeing in 1.3.

Regards.

Hi

Running it as root gives it root permissions and priority so it will be more rescource hungry.

Either renice it or do not run it as root.

But if is the reason, why I didn??t see any improvement in 1.4 or in a monothreaded application
