Limits

[sm2017]

@walkor if we have many powerful machines
How many gateway and business worker can exist in workerman system ??

If we choose libevent or event as main event loop

[walkor]

Generally speaking , For each machine
gateway->count = the_count_of_cpu_for_current_machine;
and
business->count = the_count_of_cpu_for_current_machine*2;
is the recommended value.

No I ask about connection limits . As you know each gateway is connected to business workers and vise versa . So if we increase gateways each business worker must handle more connections

My question is about distributed system

[walkor]

In theory, the number of gateway processes can't exceed 1000, and business can't exceed 60000 In the whole distributed system.
In fact, I think the best number of gateway processes is less than 200, and business is around 200-600 In the whole distributed system.
I don't have so many servers, so the above data is my guess value.

Can you explain why??

In theory, the number of gateway processes can't exceed 1000, and business can't exceed 60000

How you calculate 1000? And 60000?
If we use select we have a 1024 limitation but for event and libevent the limit is 100k (if I'm wrong correct me)

Please explain in details .Please check your Gitter , I want to chat you

[walkor]

src/Lib/Gateway.php called stream_select in getBufferFromAllGateway method which limit gateway process count can not exceed 1000. Of course, this can be changed to use event to process.

About business count , 60000 is not inaccurate. It is limited by open files of linux kernel configuration maybe 65535 or other values.

To handling 100 million concurrent connection , is there any recommendation?

[sm2017]

@walkor please reply

[walkor]

Don't put all 100 million connections in the same cluster.
You can scatter connections in multiple clusters.
There is no business communication between clusters is better.
