===============================================================================
SPEC has discovered a code defect in the SPECweb99_SSL test harness run on
the client systems used in this result. The defect prevents these client
systems from generating the correct SPECweb99_SSL workload. Specifically,
the defect in the SPECweb99_SSL code results in the clients not generating
any of the required SSL ClientKeyExchanges during the benchmark. Therefore,
the results presented here are not comparable with any other SPECweb99_SSL
results.

Network Notes
The tg3 driver was used for the network controller. This is the default for RH 7.3.
Three switches used because the clents have fiber adapters and the SUT has copper switches.
- The clients were connected to the ACESwitch with fiber cables.
- The ACESwitch was connected to the Summit switch with a fiber cable.
- The SUT was connected to the Summit switch with a copper cable.
