May I know how many instances are there in crdb/tidb cluster and the concurrency in the benchmark? We found that for small clusters (for example 3 instances), CRDB could be fast in read-only workload. Because CRDB is single binary, about 1/3 read operation will not involve RPC. TiDB need to involve a RPC for every request. For larger scale cluster or high concurrency, it is a different story.
