Dual CPU performance comparison. • This data again illustrates the increased power of the Pentium Pro processor with 32-bit Windows NT applications. It also demonstrates the benefit of large L2 cache in the Pentium/133 and /166 CPUs (as opposed to the smaller cache in Pentium/100 CPUs.) • The overall indication is that 1500 users is about the practical upper limit for tests using this LoadSim user profile. Over 1500 users the response time exceeds three seconds.
