I notice that 16 Redis shards have been used for no-persistence case. But only 12 Redis shards used for persistence case. Any reason for this?

- lynnlangit 12y agoIn the first case (no-persistence) the bottleneck is the network throughput. In the second case the bottleneck is the disk IO. We stopped adding more Redis shards as we reached the disk IO limit with the 12 shards. Adding more shards wouldn't affect the results as the disk was choking with the number of transactions from 12 shards.
