jmeter - How many threads/users can one Windows client simulate during my load test? -

i'm planning load test of our asp/.net web application , need simulate 600 concurrent users on our system.

initially we'll running load test tools (probabaly jmeter or wcat/wast) our personal workstations windows 7/32 bit dells (dual core processors). wondering how many users can expect able simulate 1 client.

if can 200 users per client, i'll need identify 2-3 more clients test.

i wanted ask community based on experience how many users should expect per client on standard windows box.

any appreciated!

this highly depends on test plan , cannot answered easily.

if example have 500 users 1 request , have waiting timer 5 minutes, should work. if users requests without waiting, put more load on machine.

it depends on samplers in use. http requests less costly soap requests example.

it depends on listeners have active.

for normal load test have around 100-300 threads active. suggest start such number , monitor load (cpu, network) on client see how potential there is.
