Relative Score performance of Pentium/166. • The results and performance are very similar to that of the Pentium/133. • This data again illustrates the power of the L2 cache combined with the faster clock speed of the Pentium/166. It is clear that a single Pentium/166 easily outperforms two or four Pentium/100 CPUs. • The server is less quick to consume processor resource. 800 users can easily be supported with subsecond response time.
