Performance of the CTL4j ************************ a) Using the 'lib'-transport A big advantage of the CTL4j is its ability to utilize local classes directly without having to rewrite a single line of code and without recompiling if you use locs.txt or a resource manager. In addition to that, there is no noticeable performance hit in comparison to using 'normal' local classes. This means that you can split your system into components first and decide later whether or not it makes sense to run them as separate threads or on different physical machines. b) Using the 'tcp'-transport Right now, the CTL protocol implementation of the CTL4j is unoptimized, which means that you will notice a big performance hit even with minimal communication. At this point, the performance is not good enough for production use.
