> Replica placement calculations performed during collection creation take extremely long time (several minutes) when using a large cluster and creating a large collection (eg. 1000 nodes, 500 shards, 4 replicas).
> Profiling shows that most of the time is spent in {{Row.computeCacheIfAbsent}}, which probably doesn't reuse this cache as much as it should.
