Thread safety controls the read and write of resources to ensure data consistency, in other words, increases the overhead of the system. As a result, efficiency in a single-threaded environment is less efficient than non-threading, but if the data is correlated between threads, the read-write order needs to be guaranteed, in thread-safe mode.
