Hi, I have just created an issue on jira with key AXIS2-780, and I have attached the code.
I did not know about jmeter earlier, so I decided to try testing it using jmeter also, using an aggregate reporter. However, I don't find a big variance in the throughput figures that it gets. These are the values, I repeated the run three times for each number of threads. loop count 1000 10 threads - 241, 243, 259 20 threads - 237, 229, 233 30 threads - 233, 230, 227 40 threads - 227, 231, 226 I don't know how exactly jmeter runs the test and calculates the throughput, and I don't know if the overhead of the framework is levelling the figures out, because I got much larger values for throughput, particularly for smaller number of threads. My client spawns n number of threads, and each of them send r requests. My calculation was based on startTime taken before spawning threads, endTime taken after all the threads are done, and reqPerSec = ( n * r )*1000/(time diff in millisec). Is there a problem with this ? I also did a test by spawning only 10 threads from a client at a time, but running the client on multiple machines at once, and that gave me approximately the same figures, too. Also I have used exactly the same client to post to axis1.

Subramanyam, I am just now running a jmeter based multithreaded test with 1,5,50,100,200 threads and i *definitely* don't see what u are seeing. Could u please create a JIRA issue and upload both your service and client code? -- dims On 5/29/06, Ramanathan, Subramanyam <[EMAIL PROTECTED]> wrote: > Hi, > > I've been running a few performance tests on Axis2 to compare it with Axis1. > I've found that when I post requests using a multithreaded http client [ that > spawns multiple threads each sending a certain number of requests ] , the > performance of Axis2 seems to degrade, whereas that of Axis1 seems to be > relatively stable when tested using the same client. > > Here are the figures I have got.
