This value was used because it shows the amount of memory available at the end of the test, which gives a good indication as to whether or not performance could be improved by adding memory. The "Connect Ops/sec" measurement in Tables 4 and 7 is computed by dividing the "Connections Received" perfmon measurement at the end of the test, less the value at the beginning of the test, by the total time the test ran. This computation was necessary since ILS does not create a perfmon ILS Connections/sec measurement. The "CPU Utilization" measurements for each of the ProLiant 7000's CPUs are shown in Tables 7 through 9, with the "P" indicating the processor number.
