I removed all listeners, only the HTTP request is up in the test. set the Xms32m Xmx64m and page to 32 . Same 6.7 MB file and started 10 concurent downloads. I am still getting the out of memory. I am more then sure i dont have the necesary background to solve this in time. Guess i will just have to use ab or httperf again, even tho my boss will not like it .
Anyway thx for the help Sebb-2-2, btw if you have time and you are in the mood to point me to an example/test that is doing concurent downloads of huge files :D We are hosting video files mainly , for one of the biggest internet media players, and usually they dont have files larger then 1 GB, but we have one of the main players in blogging launching a plugin soon, and i wanted to do some performance testing so i can draw some guidelines for the boss . Managed to do all other tests with JMeter, and the results are close to AB and httperf results , but i cant get the download part working with jmeter . sebb-2-2 wrote: > > JMeter currently stores all the data from a sampler in the sample > result; if you have a listener that keeps the data (e.g. Tree View) > then you will soon run out of memory. > > Please read: > > http://jakarta.apache.org/jmeter/usermanual/best-practices.html#lean_mean > > and > > http://jakarta.apache.org/jmeter/usermanual/component_reference.html#listeners > > On 15/02/2008, shimo <[EMAIL PROTECTED]> wrote: >> >> Hello, thx for the answer . >> >> Well is not related to Connection timeout at all. >> >> Is the beautiful HEAP SIZE.
