Re: [Openstack] [Swift] PUT requests sensitive to latency?

Shrinand, I have done some tracing work here and you maybe interested to try. This new patch can help you to record timing of each hop of request if you enable it in log options. This might give you more insights and help you to diagnose network latency problem. https://review.openstack.org/#/c/93

Hi Li, The problem here is that db.service_get_by_compute_host() requires admin context. [1] The live_migrate command needs to check that both hosts have a running nova-compute service before it begins migration. Perhaps the live_migrate task is passing the incorrect context in for this database q
