Chapter 6 A performance study on host-backend communication
This paper discusses the interface between host computers and database backends. The logical interface (single tuple vs set transfer) and the communication characteristics (data rate, overhead) together with their effects on throughput, response time and host CPU offload are investigated in a simulation model.
In addition, the relationship between query characteristics (number of I/O transfers, internal processing time) and throughput and offload effect is also studied.
