How do you know when you are running to many instances of a WO App on
a given server?
I understand that you obviously can't run more instances than you have
memory to work with. So if you have 4 GB of memory and your running WO
Apps consuming 256 MB per app, obviously you can't run more than
roughly 16 apps.
I realize that the number of processors is also going to play a role
in this. Just because you have enough memory to run 16 apps doesn't
mean that's your ceiling. If you have only two processors, then you
can at most simulateously handle 2 operations. In this case do you
just monitor your CPU usage and once you start approaching 50-75% CPU
utilization on a constant basis then you know you are running the max
number of instances you should be running.
What do you guys who deploy large applications with millions of
requests per day look for when determining exactly how many instances
to run on a given server.
Thank you for your time,
Eric Stewart
