Chapter 11, Problem 26E

Explanation of Solution

Transaction processing benchmarks:

• Performance will be major criteria for the end user of the CPU’s and the performance measures are being benefited through the benchmarks that are constructed by the SPEC.
• Another class of end user whose major area of concern could be the software that are wide applied in server that are used in processing multiple transactions at a particular amount of time by different users.
• The users are very much interested with the system that is capable of processing short tasks simultaneously.
• Standardizing the analysis of the performance measure of advanced system troubled the manufacturers greatly.
• The results that is produced were being flashed at instant among the potential customers but the output that is provided are not meant for the public user rather they are used in midst of the manufacturers by creating a twist in their products.
• IBM created a benchmarking system called “TP1” (Transaction Processing) and it became popular among its user.
• Thereby, the competitors began to use the TP1 for checking their performance aspects related to their system.
• The main disadvantage of the system is that the best performance has been reported are obtained achievable only at the ideal situations.

Comparison that is made between the similar system by establishing restriction and without restriction:

• The metric of the TPC-C is used to indicate the number of transactions that are being processed in a minute.
• The unit for measuring is denoted as “tpmC”.
• The ratio of price and performance are also considered as the part of results that is obtained using TPC-C.

Consider the different organizations,

• The cost of system is considered as $\$90,000$ and the throughput produced is considered as $\text{15,000tpmC}$.
• The cost of system is $\$18,000$ and the throughput produced is raised and considered to produce $\text{60,000tpmC}$
