性能测试培训_性能测试工具Avalanche

Creating a New Test
Quick = minimal configuration, minimal control
Advanced = full control over all aspects of configuration, maximum complexity
Avalanche Building Blocks
Layer 4 - 7 Testing
Layer 4 - 7 Performance Metrics •Connections/sec •Transactions/sec •Max number of concurrent users (open TCP conns) •Average time to setup TCP connection •Goodput (Object size/time to transfer)
Client Load Profile > Load Specification Types & HTTP Versions

•Test configs are broken down into Projects (upper level) and Tests within the project. • Certain tabs are shared among tests within a project: • Client •Actions •Profiles •Subnets •Server •Profiles •Transactions •Subnets

Avalanche - Clients and Servers
¾
Avalanche emulates clients establishing thousands of user transactions per second. ¾ Reflector emulates hundreds of application web servers. ¾ Supports the functional and performance testing of:
Client Load Profile - Specification
HTTP-Versions
•
HTTP 1.0 vs. HTTP 1.1
¾
Primary difference is Persistence
• A technique that keeps the TCP connection open after an initial HTTP exchange

General Steps Create a Load profile, create a URL list (Action), create all user Profiles, setup all address Subnets and host addresses. Decide which Ports you want to use in the test Assign (Associate) user Profiles and Subnets to the interfaces Network tab allows control of TCP stack Note that all Actions, Profiles, etc configured in a test are available to be used by any other test under the same project
