The graph of this run is displayed in Graph 3. 1100 1000 900 800 700 600 500 400 300 200 100 0 Run #4 in TPM 1 12 24 32 36 48 56 72 V irtual C lients Base Run Base + PCI NICs Graph 3: Base Run with PCI NICs The percent difference increase in TPM from the base reached 29% at 32 virtual clients then leveled to around 16% increase from the base system at 72 virtual clients. The burst in TPM at 32 virtual clients to 36 virtual clients comes from garbage cleanup of the firewall system. Improvements are caused from the PCI bus speed being faster than the EISA bus. The average failure rate for all runs is under 1%. DNS Lookups for HTTPD, HTTPD Cache DNS lookups turned off for Run #5 results in an average overall percent increase from the base system in TPM of 4%. Peaks from the base system of 16% to 31% TPM increases are attributed to time just after system cleanup procedures. Since HTTP and FTP are tested in this run there is 16
