Hello Community, We've two zones with Reef (v18.2.1) and trying to sync over 2 billion RGW objects to the secondary zone. We've added a fresh secondary zone and each zones have 2 RGW dedicated daemons (behind LB) each and only for multisite; whereas others don't run sync threads. Strange thing is that during the sync, the master zone LB records only 1k to 1.5k HTTP requests per second from secondary zone RGWs and not more than that. This behaviour leaves us with less link utilization. I don't see any noticeable issues with the link, cluster or RGW daemons on both ends. We've already increased rgw_data_sync_spawn_window, rgw_bucket_sync_spawn_window, rgw_meta_sync_spawn_window values to more than the defaults and don't seem to improve. Has someone noticed this behaviour of secondary zone RGW daemons fetching only around 1k to 1.5k objects per second? Regards, Jayanth
