Performance: one service worker can only process one task per second?

I have a ServiceContainer with only one worker, as below:

config = {
        AMQP_URI_CONFIG_KEY:AMQP_URL,
        MAX_WORKERS_CONFIG_KEY: 1,
}
ServiceContainer(service_class, config)

After sending async calls, I started the service as the consumer. But it turns out that the only one worker can do exactly one task per second, is there something wrong with my configuration?

The service simply returns a number:

class Consumer(object):
    name = 'test'
    @rpc
    def work(self):
        logging.info('hello')
        return 42

logs:

[I 170314 20:39:25 main:26] hello
[I 170314 20:39:26 main:26] hello
[I 170314 20:39:27 main:26] hello
[I 170314 20:39:28 main:26] hello
[I 170314 20:39:29 main:26] hello
[I 170314 20:39:30 main:26] hello
[I 170314 20:39:31 main:26] hello
[I 170314 20:39:32 main:26] hello
[I 170314 20:39:33 main:26] hello
[I 170314 20:39:34 main:26] hello
[I 170314 20:39:35 main:26] hello

agreed. @mikegreen7892003 would you like to make a pr bumping it to max_workers + 1? (if not, i’m happy to but it was your idea)
