Performance Test Experience Series One: I understand the performance test

The concept of performance testing, I will not say, Baidu a bit, will come out a large pile, each statement has a certain truth. What is a performance test? Please do not tell me to test the performance of a Test object:), performance testing, as far as I know, many times it is difficult to locate, there are a lot of things may be stuck in the pace of our progress! Now that we have a general idea, I understand how to do it for a new feature to go online.

First of all, if we have the best to do the next single-user automated testing, to daily check, the performance of the new features. Can not be automated to complete, but also to complete the manual.

1) new feature settings become a thing, to combine HttpWatch, or other developer tools to monitor every request, even the number of request.

2) If the art (average transaction response time) is high, has been rejected by the customer, there is really no need to build the environment and so on, the performance test prepared.

What if art is high?

Ideas, first look at the background network server, app server, etc., start the runtime Server.log,legacy.log set is nohup.out whether there is an exception

In addition to view the request has a single request very high situation, and then first to exclude is not caused by the network, have encountered some request and other not in a network environment, if so, it is simple, you can configure LB VIP (some company permissions restrictions, May need help from the network department), etc. to solve (complex balanced virtual IP) can make the network segment can be accessed.

What if none of the above questions are done? We can go to do jprofiler, see if there is a problem with the code, haha this problem is more complex, need to go to the actual combat.

Write here for the time being here today, not to be continued!
