Phil, what date is the next release scheduled for?

Subject: Re: [Grinder-use] Load Test for 2000 Scripts  Parallel


 
I just received 20 machines (with 2GB of RAM each), which I am going  to use for scalability tests and later for functional tests. 

I was able  simulate around 500 light-weight grinder agent threads on an old machine with 1  GB RAM before I ran out of virtual memory. I started them in 5 separate grinder  processes with 100 threads per process. In my case test scripts are pretty slow  (they simulate real, not "caffeinated" users), so I was memory-bound and not  CPU-bound.

I am planning to start around 800-1000 grinder threads on each  of the newly received machines. So, my total will be 16K-20K individual virtual  users.

there    is no way a normal PC will handle 100 JVM process!


To handle this    much load u will need to have a array of test machines each
running the    grinder agent with a single JVM. From my latest tests i am
using XP + intel    2.5GB. It reaches 80% CPU with something like    the
following

grinder.processes=1

grinder.threads=500

So    are loking for around 40 PC to use a grinder    agents.
