Performance testing entry - concept papers

Performance Testing & Load Testing & Stress Test

1. Performance test performance test
   • By tools, get performance index value of the system in different conditions
   • Such as: How long do you run 100 meters?
2. Load testing load testing
   • By gradually pressurized to observe the operation of the service
   • Such as: to see you have a few two kilograms
3. Pressure test pressure test
   • Under certain workloads, continued to run a relatively long time, view system stability
   • Such as: the recent big working pressure

Strength test & Capacity Test

4. Strength test
   • In particular, low system resources system operation, where the purpose is to find the first failure
   • Bucket short board
5. Capacity Test
   • Under certain resources, different data of the order, the values ​​of certain indicators of the value of the performance of the system

System users & Online user & concurrent user & Threads

1. System users
   • The number of registered users of the system: narrow
   • Broadly: the number of users since the history of all the visited system
2. Online users
   • Narrow: user currently logged on
   • Broadly: the user is currently accessing the system
3. Number of concurrent users
   • The number of users the same time point, requests execution of the same
4. The number of threads (a Virtual User)
   • The number of virtual user performance testing tool for simulating user

TPS & QPS

1. TPS (TransactionsPerSecond) by the number of transactions per second
   • Services: refers to a client sends a request to the server and then the server process to respond
   • To complete the second transmission request response to the request is received, the total quantity, is the value of the TPS
2. QPS (Queries Per Second) queries per second rate, or rate request
   • The number of requests per second inquiry initiated by the server
3. difference
   • Transactions may have a more Queries, such as accessing a web page

Throughput Throughput &

1. Throughput transaction / s
   • The number of users the system requests processed per unit time.
   • Such as: port throughput, we often say that the total port handling operations 1 year
2. Throughput Kb / s
   • Average rate data per unit time
   • 90% 95%
3. difference
   • Parallel average throughput per unit time

Response time = t1 + t2 + t3 + t4 = t2

• Network server to initiate t1
• Processing server response time t2 + t3
• The server returned the initiator network t4

Note: The performance tests do not consider rendering time.
