From Figure 9 and Figure 10, we found that there were three interesting characteristic results. 1. The speed up and efficiency were decreased when the number of workers increased, for example, 100 jobs testing. This characteristic happened because all workers in system are not fully utilized. For example, in 32-workers system, it had to use 4 iterations to finish 100 jobs (32+32+32+4 = 100). So, in the last iteration, there were 28 workers free. Assume that 1 job used 1 second for executeing. The speed up was 25 (Ts/ Tp = 100/4 = 25), and the efficiency was 0.78 (S/ P = 25/32 = 0.78). If we submitted 128 jobs (32+32+32+32) to this system, the speed up and efficiency would be 32 (128/4) and 1, respectively. 2. The speed up and efficiency were almost perfect. The perfect speed up was the speed up that was equal to number of workers in system. The perfect efficiency was the efficiency that is equal to 1. Basically, the communication overhead
