[one-users] OpenNebula ageing effect?

[Ruben S. Montero]

Hi

Yes I agree with Steffen, I'd be surprise this is something related to DB
access. A couple of thoughts from your data:

1.- Prolog Times constant means that your are not suffering an storage
problem
2.- Pending Times increasing. This depends on the number of VMs to
schedule, and the number of available resources. The default scheduler
parameters are quite conservative in order not to overload the other
systems but this can be tunned considering each setup. There are huge
improvements in performance in OpenNebula 2.2 and OpenNebula 3.0 in this
area.
3.- Increase Boot times depends directly on the hypervisor. This usually
increases when starting multiple VMs in the same host at the same time.

Cheers

Ruben
