Today I would like to introduce to you a small performance testing tool, Microsoft's WAS, which is easy to use.

Webstress is a relatively simple and easy-to-use tool, because it can not set parameters, it is only suitable to simulate some fixed network address connection stress test, it is recommended to use Loadrunner. At present, Microsoft no longer carries on the version upgrade.

Manually create a script

-

File- > new (Ctrl + N)-> Manual

Enter the server name or address and comments in [Server]

Select the method passed by HTTP (Get Head Post)

Enter the test path (Path)

Modify the group you belong to (Group is optional)

OK

Record a script

-

File- > new (Ctrl + N)-> Record

Set the default browser and clear Cache

Select the project to be recorded and click Next- > Finish

Access the test address and link to be tested

Modify the group to which each link belongs (Group) optional

Click Stop Recording

-

Script Edit Tree

Item delay can be thought of as Thinking time unit (ms)

Group more realistic simulation of the actual operation, interlacing and clicking at the same time

Verb (Post Get Head)

-

Concurrent connection Settings (Concurrent Requests)

Script Tree- > Setting

Number of clients created by Stress level (threads)

Stress multiplier (sockets per thread) number of concurrency per thread

Total Concurrent Requests = Stress level (threads) x Stress multiplier (sockets per thread) = Total Number Sockets

-

Request delay setting (Request Delay)

Script Tree- > Setting

Used to simulate and coordinate the actual bandwidth

Unit (ms)

-

Set bandwidth (Bandwidth)

Script Tree- > Setting- > Bandwidth

-

Data analysis

Number of hits: the total number of clicks on the page by virtual users during the test interval

Requests per second: number of client requests per second

Threads: number of threads, that is, virtual user concurrency

Number of Socket Errors Connect:Socket incorrect connections

Number of Socket Errors Send:Socket error transmissions

TTFB Avg: the average between the first request and the first byte of the server reply data received by the test tool

time

TTLB Avg: the level between the first request and the last byte of server reply data received by the test tool

Average time

Remarks

1. Cannot add real simulation data to test Web Page Download Performance

two。 Cache factors affect the accuracy of test records

3. Adjust the Webtool service Administrative tools-> Services to manual

4. WAS.mdb under the WAS directory of test data
