I have a same j2ee application running on two almost idential solaris machines. One is constantly faster than the other one by 4 times. What can be the problem ?

Hi,

Is your application getting Data from another machine (like a database on another server in the network)? Maybe the app is idle just waiting for stuff.

Other than that I can only suggest performance testing. As I heard in a training course "Always test performance improvements on the production machine" (which means that if you do performance improvements on your development pc, it is not guaranteed that it's also an improvement on the live machine)

Hi Raj

Have you checked if the load on the machines is the same. I mean if you check the web server logs do you see around the same number of requests on both the machines.

It could be that your load balancer is skewed in some way to give one machine more load.

Just a guess...
