    Description

      1 bucket x 100M x 2KB, 1 x 1 views, 10K mixed ops/sec, 400 qps

      It happens in all rebalance cases (in/out/swap/failover), so it's either 3->4 or 4->3.

      Not a new regression, I can see this issue in many 3.0 builds.

      The latency is normally low but there are few occasional spikes. In 2.5.x peak latency was about 1-2 sec.
