multiple simultaneous requests

[agalera]

He was performing a test with meinheld, I was trying to test whether it is possible to address several requests at once. I see that the server listens only 1 to 1.

Is there any way to change this? I would like the requests received have the same context and not try a fork process.

I tried to use gunicorn + meinheld, now if I can handle several at a time, but do not share memory for me is a problem. I tried to put --threads 10, but to indicate that parameter only serves 1 to 1

from bottle import run, get
import time


@get("/test_yield")
def test_yield():
    print("init test_yield")
    for x in range(10):
        time.sleep(1)
        yield(str(x))
    print("end test_yield")

if __name__ == "__main__":
    run(server="meinheld", port="9876", host="0.0.0.0")

init test_yield
end test_yield
"127.0.0.1 - - [30/Jun/2016:11:32:59 +0000] "GET /test_yield HTTP/1.1" 200 10 "-" "Mozilla/5.0 (pc-x86_64-linux-gnu) Siege/3.0.5"
init test_yield
end test_yield
"127.0.0.1 - - [30/Jun/2016:11:33:09 +0000] "GET /test_yield HTTP/1.1" 200 10 "-" "Mozilla/5.0 (pc-x86_64-linux-gnu) Siege/3.0.5"

While meinheld supports greenlet, I think prefork is better way for most use cases.
I think gunicorn + meinheld behind nginx is the best practice you should consider first.

but do not share memory for me is a problem.

Why? How many processes do you use? What is your app's bottleneck? (instead of time.sleep()).

[agalera]

I need to have a list of users connected by websocket to be able to broadcast to everyone. For this I need everyone to have the same context

The server receives POST requests and send this information to all websockets. Therefore it is necessary to share memory, if not, could not send to all users.

[methane]

You shouldn't use meinheld's websocket.
It is very experimental and based on old spec.

[methane]

asyncio or Tornado is what you should use.

I tried Gevent, is quite similar to meinheld and if I get the part concurrency. I am sorry not to use meinheld :(

[agalera]

from meinheld import patch
patch.patch_all()

solved :)
