Program When writing HTML for static pages generated by ASP pages, if a large number of pages are generated at the same time, the progress bar at the bottom of the browser must display 3%, 6%, 10% and so on. In this waiting process, you don't know which record the page has generated, and you can only stare at it.
If you know response. Flush and response
Performance testing is an important engineering project in software testing. Sometimes we need to test the response time of web pages, httping is an open-source software dedicated to testing the response time of web pages.

ObjectiveRequests request, the interface response time, but also we need to pay attention to a point, if the response time is too long, it is unreasonable.If the server does not respond in a timely manner, you can not wait until you set a timeout time.About the response
In the previous section, we talked about throughput. As a user, you don't have to worry about throughput, but the response time is the main embodiment of the user's perception of system performance.
From the user perspective, software performance is the response time of the software to user operations. To be more spe
Some things are not complicated, but we do not pay attention to him, or we do not have a good concern, we use LR to do performance testing when there is a very important indicator, response time, we all know this indicator, but also know that this indicator can be found in the results analysis, But how many people know how these values are derived from LR? Today in this article I will give you the secret of
Why to monitorService interface is to provide service, interface correctness, stability is the most important, in ensuring that the correct and the need to maximize the interface response time.Some teams have specialized tools to monitor system response time and throughput, but if the team does not have this "treatment" it will need to do some tools to service it
Python uses pycurl to monitor http Response Time script sharing and pythonpycurl
Recently, we need to monitor the node to the source station. Simple ping can detect some things, but http request check is also required. So we studied pycurl.
Pycurl is a python library implemented in C language. Although it is said that it is not so pythonic, It is very efficient and supports many protocols:

request package, and Displaypage to the requested client to send a reply packet. Regardless of the processing time of the actual business, the client can get a response at least to wait for the 4 log to print time. If we remember that the processing time for a request is m, and the client waits for a
Recently, a customer responded to the client card. The boss gathered a meeting of technical staff to discuss the cause of the slow response, which resulted in Analysis of nginx response time. Because the nginx log format in the online environment is enclosed in quotation marks, processing is a little troublesome. The following is the processing process.

phpMyAdmin time-out or slow response reasons I analyzed there are two, time-out is set time is not enough, the default is 1800 seconds, and the slow response is phpmyadmin automatically check the update caused, let me specifically solve the operation method.

Now there are many processes involved in the process of lengthy and time-consuming response, such as access to WebService, remote calls, complex processing, and so on, if we use a direct sequential execution of the process may cause the interface to pause, response stop, unnecessary waiting for defects, this is not the case.

Label:"Response Time" is a common metric for measuring database performance.

When testing a search engine, we usually use a large number of search keywords. Sometimes it is necessary to know the response time of each keyword in the case of concurrent access, generally, if you do not process the script, you can obtain the response time of each keyword, but these times do not correspond to the co
Premise: When we design the mouse click event, drag the window, when we set the detection target waiting for the results to return, when we open a page to view the content, how long is we able to accept it? There is no academic theoretical research support. This article will give you an answer.PS: The academic support of response time, at least 2 days to spend without Google. Now accidentally found and coll
Example: A high-speed road with 10 entrances, each entrance can only be 1 vehicles per second1. How many cars can I get in 1 seconds? tps=102, how long does it take for each car to respond? reponse time = 13, change to 20 cars, how few per second? How long is the response time for each car? TPS = 10,reponse time = 1
