load-testing

问题 I am using JMeter(in distributed mode) for load testing. Its a JAVA application and SQL database. Application server and database server are two different images. If i put 50 user's load, after 60 minutes application server reaches 100%. If i put 100 user's load, after 60 minutes application server reaches 100%. If i put 500 user's load, after 60 minutes application server reaches 100%. If i put 1500 user's load, after 60 minutes application server reaches 100%. If i put 2500 user's load,

问题 I have a node service that streams data via SSE (https://www.npmjs.com/package/sse-channel). I would like to loadtest this service my making 'n' concurrent connections, i tried the "loadtest" npm module but since we are dealing with streaming responses i was not able to report back any data like requests per second, mean latency etc… when the streaming requests are made, is there a way to use "loadtest" module for streaming services if not can someone point me to the module that would report

问题 I tried the following in the Bean Shell Sampler; Runtime rt = Runtime.getRuntime(); rt.exec("cmd.exe /c && cd /Program Files/Java/jdk1.8.0_51/jre/bin & java -jar File-2.0-SNAPSHOT.WAR"); It looks like, it is not able to run.. Am i doing in the correct way? 回答1: If you need to do it with Beanshell, I would suggest the following amendment to the process command line: cmd /c start java -jar ..... See cmd.exe documentation for more information However in majority of cases it might be easier to

问题 I'm using Visual Studio Online Load Testing to test an API with variable parameters coming from a CSV file. My setup looks like this: In properties I set "Show Separate Request Results" to True, hoping that I would be able to see which parameters were used during the test, but I cannot find anything on this in the report? Is this the way to do this or am I doing something wrong? 回答1: Visual Studio load tests are not great at showing how individual test cases worked. The test case logs show

问题 First of all i am new to testing. I want to perform load testing on web api's [ around 70 ]. I am using VS2015 Enterprise that comes with load testing feature but i am not aware how to use. Steps that i want to perform are: 1) Response time of the service when running a single request. 2) Memory consumption used by the service when running a single request. 3) Maximum number of concurrent requests supported by the service 4) Memory consumption used by the service when running the maximum

问题 I posted this question asking why 100000 run () calls is faster compred to 100000 start () as i found out that despite multi threading, 100000 start would actually take longer than 10000 run calls because of the thread management. Actually, i was trying to spawn 100000 threads to simulate a load on an EJB method i wish to test, and it seems not possible this way. Is there a way which i could achieve this? Or is it that i would need to have multiple machines in order to achieve that load. Is

问题 I need to test Oracle ERP system module which runs on Linux server and uses oracle as a database. I have some past experience with web performance and load testing however I am not sure whether Visual Studio 2012 is capable of capturing server side performance counters when it comes to linux platform and oracle data base profiling and tracing counters. so following are my questions : Can I capture server specific counters using vs 2012 ? Is VS 2012 capable of oracle sql tracing and profiling

问题 I'm creating a load test, and I have done this so far: threads-100 ramp up period- 100 loop - 2 My understanding is that 1 thread will be fired per second, and after the first batch of 100 threads is done, another round of 100 threads will be fired in the same way, with the difference between their firing period as 1 sec(same as the first loop). Is this correct? Also, what would be the case if I had this: threads-200 ramp up period- 200 loop-1 Does it mean 1 thread per second and a total of

问题 I have been carryout load test on an API service deployed AWS EC2 instance. The service is deployed on two boxes (each c4.8xlarge) and is being load balanced. Test is carried out using JMeter in distributed mode where in test agents are also aws and are m4.4xlarge machines. There is no EBS storage used. Each sample response is of size 315 bytes and I receive about 12k/sec throughput with testing run on 200 threads. In anticipation of receiving higher throughput I increased the threads to 450

问题 A server offers a SOAP function call interface. Hundreds, perhaps a few thousand, of PCs call that function. I need to load test this using a single PC. At the moment I just have a for loop. Is that good enough? If not how can I make the test more realistic? I had thought of threading, but if the SOAP function call is atomic then that doesn't buy anything. Even if it does, there can still only be one active thread (per CPU) on my tester PC. I hope that is clear, please ask for further info if
