3.7. Microsoft SQL Server 2005
In this experiment, the DVD Store benchmark was used to drive the Microsoft SQL Server® 2005 database. This benchmark
simulates online transaction processing of a DVD store. Sixteen simultaneous user sessions were used to drive the workload. As with
the previous benchmark, this workload has a mixture of CPU, memory, disk, and networking resource requirements. Microsoft SQL
Server however issues many RDTSC instructions, which read the processor time stamp counter. This information has to be recorded at
the primary and replayed by the secondary virtual machine. As a result, the network traffic of this workload includes the time stamp
counter information in addition to the disk reads and network packets.
