• Successful Rounds, a successful request
• Failed Rounds, failed request
• Successful Hits, number of successful clicks
• Failed Hits, number of failed clicks
• Hits per Second, clicks per second
• Successful Hits Per Second
• Failed Hits Per Second
• Attempt Connections, try connection number
• Throughput, throughput rate

c/S Indicator:

• User Connections, number of users connected
• Number of deadlocks, database deadlock
• Butter Cache hit, the name of the database cache

The basic process of performance testing:

• Identify performance testing requirements
• Develop performance test scenarios
• Write a performance test case
• Perform performance test Cases
• Analysis results
• Generate reports

1.2 Open source Web performance test
