Vertical Scalability
A customer has a p690 with 32 processors and 32 Gig of RAM. Two of his
engineers are arguing over how many copies of the applicaiton server to
run on the machine. The application has proven to scale well but session
persistence has shown a small overhead when used with no session affinity.
There are no other applications running on this machine to compete for
resources. One engineer wants to create one big JVM with 32 Gig of RAM
assigned as max heap (assume this is possible, tell me why if it isnt).
The other wants to create 32 JVMs, one for each CPU.
What is your advice?
What are their arguments?
