Description of problem: Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. create 95 host environment with 300 vlans on one host interface (non mgmt) 2. Setup: - No REST calls - VdsRefreshRate=default - Host in UP status 3. let engine run idle for 15 minutes after startup 4. measure load time of: - webadmin host interface list view page - 'curl <engine>/ovirt-engine/api/hosts/<host>/nics' Actual results: webadmin freezes, REST call takes long minutes to return Expected results: no more than a few seconds to complete both flows Additional info: https://docs.google.com/document/d/1-Mv2JjDkV2gKiXsomVKCtMf5r4TZbxjiFRtbygBd-fU/edit?usp=sharing
typo in description. Should be: Expected results: approximately 2 minutes to complete load of web page and get REST response
