Hi Roberto,
This change is within a factor of 2 of your existing load. I would start with
analyzing the load on your existing system to determine where your bottlenecks
are. 5M/day is 57/sec evenly distributed or 174/sec in an 8 hour period. This
does not seems like a lot, but you have given us no details on your actual
workload.
Regards,
Ken
