Performance Test Practice-linux

1. Requirements: On-line system performance optimization, locating servers and online system bottlenecks
2. Based on on-line experience data and expectation quantification
3. Data
   

   	Up	Down
   On-line data	50	500
   Test data	100	500~2000+
   Test data	200	500~2000+
   Test data	300	500~2000+

4. Tools: Top, Ltrace

Top: Enables real-time display of resource utilization by processes

Ltrace: A library function call that can track a process that shows which library function is called

Gdb

5. Automation implementation:

• • • Up for 100,down from 500 to 2000, analysis log, graph
    • Up for 200,down from 500 to 2000, analysis log, graph
    • Up for 300,down from 500 to 2000, analysis log, graph
