I'd be included to add more guests I think, just figuring z/VM does it better
than Linux :)

Thanks Ingo (and Scott)!
1) The app runs under IIB
2) We're running z/VM 6.3 (soon 6.4) in a four-member cluster
3) We have more real IFLs in each member than vCPUs on any of the guests
4) We have a ways to go before we get to the 64-CPU limit
My main question is how well Linux itself scales as
Up until now the openJDK has only been able to operate in interpreter mode.
Thanks to the good people at SAP the fruits of their 10 years work on the JDK
have resulted in code being pushed upstream that enables JIT compiling. Fedora
rawhide have a source RPM but, currently, only builds the “zero
It really depends on the workload whether scale-up or scale-out is better
suited. With z/VM 6.3 you should be well prepared for both options (as you
are with running Linux in LPAR) but it is really a workload question. E.g.
many applications would allow for scale-out clustering at linear scale,
whi
First - how many 'real' CPUs or IFLs do you have ? You don't want
more virtual defined to a guest then you have actually defined to z/VM..
(I'm assuming z/VM here)

We have eight RHEL 6 servers with 8 vCPUs each handling a large workload, which
continues to grow. We could expand the server farm horizontally by adding more
servers, or vertically by adding more vCPUs. I'm concerned about SMP effects of
adding more vCPUs but don't have any data to
