 When TPC is enabled, clients using the `ALL_MEMBERS` cluster routing mode connect to the number of cores specified in the client config. If TPC is enabled on both client and server, clients connect directly to one of the TPC threads instead of using the legacy network threads. TPC-enabled servers continue to use the same ports for discovery, which means there's no difference in how the cluster member list is created and TPC-aware servers are backward compatible with clients that don't use TPC.
 
-NOTE: Clients using the `SINGLE_MEMBER` cluster routing mode ignore TPC and connect to a random member in the cluster. Your clients must use the `ALL_MEMBERS` cluster routing mode with TPC.
