Benchmark

Test device: macbook pro 16 2021 with Apple M1 Pro, 16G Mem
Robots number: 6000
Send message frequency: 2 messages per second 
Save Mongodb frequency: 12k per second

• The machine cpu and memory usage are as follows:

  CPU usage: 15.16% user, 30.77% sys, 54.6% idle

• The process occupies cpu and memory as follows:

  PID	COMMAND	%CPU	MEM
  86643	gate	111.1	619M+
  86646	game	80.9	751M+
  86662	client_bots	71.3	679M+
  1512	mongod	30.6	160M
  71456	consul	1.9	53M-
  71121	nsqd	0.2	12M
  86656	mail	0.1	38M

• The MongoDB operations performance are as follows:

  

• The players' message processing latency are as follows:

  

Getting Started

• Download - git clone this repo and cd in its root path

• Start MongoDB - running in docker-compose:

docker-compose run --service-ports -d mongo

• Start Gate - cd to apps/gate, run following command:

go run main.go

• Start Game - open another terminal session, cd to apps/game, run following command:

go run main.go

• Start Combat - open another terminal session, cd to apps/combat, run following command:
