The content of performance test is briefly introduced, and the main objective and test method of performance testing are recognized from the large frame.

1. Performance Test Indicators

• Response time
• Number of concurrent (the system can process the number of requests simultaneously)
• Throughput (such as tps-per second processing of transactions)
• Performance counters

2. Performance test Methods

• Performance testing (Design-time requirements for normal use of concurrent requests pressure)
• Load test (find throughput spikes, exceed peak, request increases, but system throughput drops)
• Stress testing (to find the critical point of a system crash)
• Stability testing (under certain circumstances, the stability of the system operation over a period of time.) Note that stability testing requires uneven request testing)

3. Performance Test Report

• Performance Test Report

Concurrency number	response Time (ms)	TPS	error Rate (%)	Load	Memory (GB)	remarks
10	500	20	0	5	8	Performance testing
20	800	30	0	10	10	Performance testing
30	1000	40	2	15	14	Performance testing
40	1200	45	20	30	16	Load test

4. Performance optimization Strategy

• Performance analysis (locating performance bottlenecks)
• Performance optimization (-web front-end performance optimization-Application server performance optimization-Storage server performance Optimization)
