Description of problem: The current value of 2 seconds is a bit low. The UI refreshes every 5 seconds. I've changed it to 4 seconds on my setup (from the default 2). The setup has ~13 hosts, 9 of which active, and it reduced the CPU load on my RHEVM by ~40-50%. I'm sure DB IO has also been reduced, did not measure it though. Need to think if on upgrade we should change the value as well. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
why not 4 ?
fixed in commit : ccb5257
