Hello Chuck , That's really good response for us . I would love to do some more test . If we have more considerations will share to you. After all , Does any suggestion of separative each workers into different bare-metals? We has only Proxy-node / Auth-node / Storage-nodes ... Could it possible to isolate more workers for better performance ? It seems quite busy of each storage-nodes . As I know , Object-server & Account-server & Container-workers should in same host(saw in Cactus Admin manual). am I right ? I believe this discussion will help more stackers on choosing SLB even entire architecture design.
