performance question

I deployed an application from one machine to another one. Both of them has almost the same memory, CPU. I use Macromedia JRun. But the speed on one machine is significantly slower than the other. It is about 10 times. What can be the obvious reason for that ? How to check ?

Maybe one machine is running more applications (using up more memory) than the other?

Could it be issues with the network?

We had a similar problem at one of my past jobs. Turned out someone was rebooting the server overnight...

You could also check on the machine type. A server class machine and a workstation would behave differently. Also machine age can turn out to be a factor. We have had instances where a solaris workstation being used as a server had better performance than an old server class machine.
