Performance Tips

7.6 Simultaneous Multiprocessing

With RTR Version 2, threaded applications could use Symmetric Multiprocessing (SMP) effectively. In RTR Version 3, SMP will not provide the performance advantages of RTR Version 2. The single control process of RTRACP in RTR Version 3 does not take advantage of an SMP conﬁguration. Similarly, because with RTR Version 3 there is only a single command server, you cannot gain advantages associated with the ability in RTR Version 2 to run command servers on different processors. However, applications can run multiple concurrent servers as in RTR Version 2.
