Description Shirly Radco 2015-03-17 07:25:40 UTC 
Description of problem:
It was reported that the aggregation of vm_disks_usage_samples_history to hourly
was running slow.  

Version-Release number of selected component (if applicable):
3.5

How reproducible:


Steps to Reproduce:
1. Install and setup engine and dwh 3.5 environment.
2. Replace the ovirt_engine_history database with the one that sradco will supply to this bug.
3. Check performance of hourly aggregation

Actual results:
Very high cpu usage when performing hourly aggregations.

Expected results:
Should normal cpu usage and not have high impact on cpu usage. 

Additional info:
Should test that aggregation is same as before.

Perform test before and after the upgrade on the same data.
