===============================================================================
SPEC has discovered a code defect in the SPECweb99_SSL test harness run on
the client systems used in this result. The bug prevents these client systems
from generating the correct SPECweb99_SSL workload. Specifically, the bug
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.
