问题 I'm using J-meter to get response time for an API via HTTP request but this API internally few more api services. Now, i need the response time taken by these internal calls too. Pls could anyone assist to get this one sorted via J-meter 回答1: Below is what I can think of:- Check on "Follow Redirect" and then use listener like "View Result tree" or "Simple Data Writer" to write the output in an XML format instead of CSV. There you can find the redirected URLs and response time. But, XML

问题 So there is something I'm missing here about how to use JMeter. I was reading in the user guide that I can use a Java Sampler to run my test. It's ok because I need to read a file with some content in it and then send it to the storage engine. So I was starting writing some unit tests to implement my version of a JavaSample using the class AbstractJavaSamplerClient. I was counting to load the file in the setup just once, but it puzzles me the fact that I can;t pass it to the runTest method

问题 I have a couple of HTTP Request setup for my Thread Group. I noticed that the first request is always taking longer than any other requests. I reordered my requests and the problem still persists. This is making it hard to analyse the response time. Is it a known problem with JMeter? Is there a work around? This is the setup that I have org.apache.jmeter.threads.ThreadGroup@69bb01 org.apache.jmeter.config.ConfigTestElement@b3600d org.apache.jmeter.sampler.DebugSampler@67149d https: 1st

问题 I am currently trying to develop a judging system that measure not only time and memory use but also more deeper information such as cache misses and etc., which I assume the hardware counters (using perf) are perfect for it. But for the timing part, I wonder if using purely the cycle count to determine execution speed is reliable enough? Hope to know about the pros and cons about this decision. 回答1: So you're proposing measuring CPU cycles, instead of seconds? Sounds somewhat reasonable. For

问题 I'm executing performance testing using JMeter and Blazemeter report, but the response time value is the same as latency time value. can somebody explain? I attach the graph results: Latency Time Graph Response Time Graph 回答1: It just means that the response is small/empty. The values are TTLB and TTFB, See explanantion about the difference Latency is a difference between time when request was sent and time when response has started to be received . Response time (= Sample time = Load time =

问题 I'm considering using locust for some of my performance tests. I'm more familiar with Python and find locust much easier to read than JMeter JMX. One thing I'm accustomed to doing with JMeter is generating my own average, 90pct, 95pct, and 99pct reports from multiple runs. To do this, I've written a script that parses the JMeter logs which contain information on every request (response time, payload size, etc.), and then combine all the runs into a single data set and generate average and

问题 By default Xcodes performance tests are run ten times and my result is the average of those ten tests. The problem is the averaged result varies considerably each time I run it so I have to run the test at least five times to get a converged result. This is both tedious and time consuming; is there a way to configure either XCode or the unit test itself to run more than ten times? 回答1: In the latest Xcode (11.0+) you don't need swizzling to change iterations count. Use the following function:
