Description
5 -> 5 UniDir, 2 buckets x 500M x 1KB, 10K SETs/sec, LAN
Similar to MB-11731 which is getting worse and worse. But now compaction affects intra-cluster replication and XDCR latency as well:
"ep_upr_replica_items_remaining" reaches 1M during compaction
"xdcr latency" reaches 5 minutes during compaction.

The last known working builds is 3.0.0-988.
