wei wang commented on SOLR-15472:
---------------------------------
We are also exploring the performance impact of excluding reads from the leader
node. In initial testing with 2 TLOG replicas + 6 PULL replicas set up,
overall query throughput is improved especially when update load is heavy.
Attach the patch tested.
> shards.preference should support leader=false
