Figure 3 gives the snapshot of average query response time of the legacy production environment for
different userloads. It can be observed that 4800 is the max userload supported within 2 sec SLA.
Figure 4 is the CPU utilization of legacy production system at 4800 userload. As explained earlier, CPU
utilization >= 90% is considered as saturation. from Figure 3 it is evident that average CPU utilization is
~93%, and iowait is ~0.13. Based on the server CPU utilization levels it can be considered that legacy
production system is almost saturated.
Hence figures 3 and 4 allow us to conclude that max userload supported by the legacy PowerEdge 2950
III was 4800.
