Enabling TLS encryption between clients and servers, as well as server-to-server communication in a distributed database like YugabyteDB, has a minimal impact on overall performance. Running TPC-C benchmarks with and without TLS encryption showed that throughput drops by less than 5%, average latency increases by around 15%, and CPU usage increases by about 6%. The efficiency of the workloads is also affected, but only within a 1-2% margin. While there may be some minor performance differences, enabling TLS encryption does not significantly impact the overall performance of the system.
