How is your storage configured/architected? Are you hitting storage on a SAN? Local disk?
As far as the objects spinning up every month, you may be referring to our monitored instances tables. We create a new set of tables for every monitored instance. That's what the _id represents and helps us map back to the COND table. I'm not aware of objects being created monthly, but if you give me an example, I can certainly look into it.
Every 10 minutes we do a couple of things: We do our stats poll that can potentially pull back a lot of data that needs to be persisted to the repo. We also do metric summarization which results in reads/writes. If you are seeing performance issues, I'd make sure you are spec'd correctly for the number of instances you are monitoring. For more specific information or analysis, I'd recommend opening an ticket with their tech support folks from your customer portal as this could get involved. 8 )
