I read in this forum Vertical clustering (adding more JVM's on a multi-CPU box) rarely helps much if the box has fewer than 6 CPU's . Well we are running our application on 8 cpus, so how can i figure out abt how many clones do i need to have for best performance of the application. Is there any specific formula for that or is it just on hit and try basis by using some load
testing tools.
The other query is regarding being WebSphere single threaded - i mean to say is that when we
run WebSphere (without clones) on Solaris using 8 cpu's, it utilizes 100% of one cpu at a given moment while other cpu's are idle. Though the process moves to other cpus' as such but at a given point of time the utilization of one cpu is 100% while others are hardly being utilized.
Sorry i forgot to mention its a Solaris 2.8 box and we are using WebSphere 4.0.3
