Figure 4. 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.
