Benchmark

采用redis-benchmark程序来进行并发测试

命令行

    redis-benchmark -t ping -p 8000 -c 1000 -n 100000

测试机型

    CPU：Intel(R) Core(TM) i5-4440 CPU @ 3.10GHz

测试代码

    local core = require "sys.core"
    local socket = require "sys.socket"
    local listenfd = socket.listen(":8000", function(fd, addr)
            while true do
                    local n = socket.readline(fd)
                    if not n then
                            return
                    end
                    if n == "PING\r\n" then
                            socket.write(fd, "+PONG\r\n")
                    end
            end
    end)
