2. TPC-C Latest Results

3. Benchmarks Standard for comparison of various systems performing similar operations Set of programs that simulate a typical workload on a given system Used to measure system performance- speed, performance, price etc. TPC: Transaction Processing and Performance Council

4. TPC Benchmark ™ A Measure performance of update-intensive database environments Transaction Profile Read 100 bytes including Aid, Tid, Bid, Delta from terminal BEGIN TRANSACTION Update Account where Account_ID = Aid: Read Account_Balance from Account Set Account_Balance = Account_Balance + Delta Write Account_Balance to Account Update Teller where Teller_ID = Tid: Set Teller_Balance = Teller_Balance + Delta Write Teller_Balance to Teller COMMIT TRANSACTION Write 200 bytes including Aid, Tid, Bid, Delta, Account_Balance to terminal

5. TPC-A and TPC-C TPC-A Throughput of system in units of transactions per second (tpsA). Cost is given as price/tpsA Released in 1988. Obsolete in 95! Moore’s law: the number of transistors on integrated circuits doubles approximately every two years TPC-C Designed for moderately complex OLTP (Wholesale supplier managing orders) Metrics: Throughput: tpmC (transactions per minute) Price: $/tpmC

6. TPS: What does it mean? TPS: Peak Debit-Card transaction performance where 95% of all transactions with 1 second or less of response time (arrival of last bit, sending of first bit) Debit-Credit Scalability: size of account, branch, teller, history function of throughput TPSNumber of ATMsAccount-file size 101,0000.1 GB 10010,0001.0 GB 1,000100,00010.0 GB 10,0001,000,000100.0 GB  Each input TPS =>100,000 account records, 10 branches, 100 ATMs
